Modular 3-Tier Display Stand Plans Made Up of Straight and Corner Units

I designed this project not as a single stand but as a display system that grows or shrinks to fit the counter and the event. The package consists of two units: one straight unit and one corner unit. In both, the three shelves slot into two sloped plates that I call shelf holders, as the guide does. A shelf holder is a single-piece plate that looks like the letter "Λ" when seen from the side and carries the slots for the three shelves along its sloped edge. The shelves of the straight unit are straight strips 25" (63.5 cm) long; the shelves of the corner unit are "L" shapes that turn through 90°. Both units rise to a height of 17-1/8" (43.5 cm) and share the same tier heights.

A multi-purpose stand: I designed this stand not just for cupcakes but to be used for many purposes. The shelves work just as well for presenting light sweets such as cupcakes, cookies, and macarons on a celebration table as they do as a sales display at a fair or market stall: jewelry, small gifts, small handmade items, and counter items such as business cards and price tags can be arranged tier by tier. When you set up the straight unit and the corner unit together, the display turns from the front of the counter to its side; your products are seen from more than one direction. The usage details are in the Capacity and Layout block.

Why two units: The straight unit builds a long row along the front edge of a counter; the corner unit turns that row through 90°, and on its own it can also sit in the corner of a room or a table. I drew both to the same dimensional system: the shelf width of 6" (15.2 cm), the tier heights, and the shelf holder profile are the same in the two units. So when the arm end of the corner unit meets the shelf end of the straight unit, the shelves continue at the same height and in the same alignment on all three tiers. The layout this project takes its name from is the U that two corner units and one straight unit make together; all the layouts you can set up are in the Combining and Layout Plan block.

Why stepped: Each shelf starts about 4-1/8"–4-5/8" (10.5–11.7 cm) behind the shelf below it. So in front of each of the lower two shelves, a strip at least 4-1/8" (10.5 cm) wide is left completely open on top; you don't have to reach under the tier above to see and take the items below. There's no supporting part in front of or above the shelves either: the shelf holders sit 3" (7.6 cm) in from the shelf ends on the straight unit and 3-1/2" (8.9 cm) in from the arm ends on the corner unit. The corner area where the two arms of the L shelves meet stays unobstructed on every tier.

How it stays up: The load rides on the interlocking joints, not on screws or nails. The notches on the back edge of the shelves fit into the slots of the shelf holders, and the two parts grip each other. The shelf's weight travels from the lower edge of the slot into the holder, and along the holder down to the table. Because the three shelves tie the two holders together, each unit acts as a single frame; on the corner unit the two holders stand at right angles to each other, so one gives its base against sway in one direction and the other against sway in the perpendicular direction.

Why glue-free: Each unit comes out of its own 2×4 ft (61 × 122 cm) plywood sheet, and its five parts are joined to one another only by interlocking joints; there's no glue, nail, screw, or miter cut. Each unit sets up in seconds and comes apart into five flat parts. You can take it as a flat package to a fair, a market stall, or a celebration, set it up in whatever layout suits that day's counter, and take it apart again when you're done.

The two units have the same height and tier layout; the area they take up on the table differs.

Straight unit: width 25" (63.5 cm), depth about 14-13/16" (37.7 cm), height 17-1/8" (43.5 cm)

All three shelves are 25" × 6" (63.5 × 15.2 cm), with corners rounded to a 1/2" (12.7 mm) radius. The shelf holders sit 3" (7.6 cm) in from the shelf ends: 18" (45.7 cm) between their inner faces, 19" (48.3 cm) between their outer faces. The base of each holder that sits on the table is 14-1/2" (36.8 cm) deep; the bottom shelf extends only about 5/16" (0.8 cm) in front of this base and sets the unit's total depth.

Corner unit: outside dimensions 19-3/4" × 19-3/4" (50.2 × 50.2 cm), height 17-1/8" (43.5 cm)

The three shelves are L-shaped, and their arms are 6" (15.2 cm) wide. The side lengths, that is, the measurement from the rounded outside corner of the shelf to the end of the arm, from bottom to top:

• 1st shelf (bottom): 19-3/4" (50.2 cm)
• 2nd shelf: 15-1/8" (38.4 cm)
• 3rd shelf (top): 11" (27.9 cm)

Between the two arms of the L, a square gap is left at the inside corner: 13-3/4" × 13-3/4" (34.9 × 34.9 cm) on the 1st tier, 9-1/8" × 9-1/8" (23.2 × 23.2 cm) on the 2nd, 5" × 5" (12.7 × 12.7 cm) on the 3rd. The back part of the shelf holders sits in this gap; it isn't shelf surface. The holders stand at right angles to each other and 3-1/2" (8.9 cm) in from the end on each arm. The arm ends of the three shelves finish in the same alignment on both sides.

Tier heights (the same on both units): The top faces of the shelves are at these heights above the table:

• 1st shelf (bottom): 4-1/2" (11.4 cm)
• 2nd shelf: 10" (25.4 cm)
• 3rd shelf (top): 15-1/2" (39.4 cm)

There's 5" (12.7 cm) of clear height between two shelves; below the bottom shelf there's 4" (10.2 cm) of space down to the table. The ends of the shelf holders rise 1-5/8" (4.1 cm) above the top shelf; if you're planning to fit the units under a shelf or cabinet, work with 17-1/8" (43.5 cm). Each shelf starts behind the one below it: the 2nd shelf about 4-5/8" (11.7 cm) behind the 1st, and the 3rd shelf about 4-1/8" (10.5 cm) behind the 2nd.

Shelf surface: With the notches subtracted, the three shelves of the straight unit give about 3.09 sq ft (0.29 m²) of surface and those of the corner unit about 3 sq ft (0.28 m²); the two units in the package together give about 6.1 sq ft (0.57 m²). The area the two units take up together is in the Combining and Layout Plan block.

The units are independent of one another: There's no part that connects the straight unit to the corner unit; you don't use screws, clamps, or any other fastener between them. Each unit stands on its own two shelf holders, and you position them as you need: side by side, back to back, turning a corner, or in a U layout. To set up one layout at one fair and a different layout at another event, you don't have to cut anything new.

How they line up: Touch the arm end of the corner unit to the shelf end of the straight unit. Because the two units share the same shelf width, tier heights, and step spacing, the front and back edges of the shelves line up on all three tiers and the row reads as a single stand. The L shelf is symmetrical about its own diagonal and its two holders are identical to each other; so there's no right or left version of the corner unit, and you can turn the same unit around and use it at either end of the straight unit.

Layouts you can set up: The dimensions are at the bottom shelf level and are approximate values by my calculation:

• The two units in the package (L layout): The corner unit goes at one end of the straight unit; the display turns from the front of the counter to its side. About 44-3/4" × 19-3/4" (113.7 × 50.2 cm), 2 sheets.
• U layout (2 corner + 1 straight): A corner unit goes at each end of the straight unit. This is the layout this project takes its name from and the one you see in the cover image. About 64-1/2" × 19-3/4" (163.8 × 50.2 cm), 3 sheets: you have the corner unit's sheet cut twice.
• Ring (4 corner + 2 straight): When you set two U's facing each other with their open sides toward each other, they form a closed display island that's seen from four directions. About 64-1/2" × 39-1/2" (163.8 × 100.3 cm), 6 sheets.
• Straight units: Two straight units side by side give an uninterrupted row 50" (127 cm) long, and three units 75" (190.5 cm). When two straight units are placed back to back with their flat backs facing each other, they form an island with a footprint of about 25" × 29-5/8" (63.5 × 75.3 cm), used from two directions.
• Corner units: When two corner units come together side by side at their arm ends, the shelves form a U-shaped area; four corner units, side by side and back to back, turn into a large tiered table of about 39-1/2" × 39-1/2" (100.3 × 100.3 cm).

Direction of the display in the U layout: In each unit the tiers rise toward the back. In the U layout the second arms of the corner units extend toward the back of the straight unit; the products are seen from the outer perimeter of the U, from three directions, while the open side of the U stays at the back. At a market stall this open side faces the seller.

Sheet: Each unit comes out of one 2×4 ft (61 × 122 cm) sheet. The cut file in the package contains one straight unit and one corner unit; for a larger layout you have the sheet for the relevant unit cut again as many times as needed. The parts of four units fit on one 4×8 ft (122 × 244 cm) sheet; all three units of the U layout also come out of a single 4×8 ft sheet.

Capacity: I'm not giving a separate number for combined layouts; multiply each unit's capacity by the number of that unit you use, and add them up (Capacity and Layout block).

Set the units up on the same flat surface, with the arm and shelf ends touching each other. Because they aren't connected to one another, a bump at a crowded counter can make them shift apart; check the alignment of the shelf ends after setup and during the day.

Capacity: I give the capacity of the two units in the package separately. When filled with a single size of cupcake, about:

• Straight unit: 260 mini, 60 standard, or 45 large cupcakes
• Corner unit: 250 mini, 55 standard, or 40 large cupcakes

I calculated these figures from the dimensions of each unit's three shelves, placing the cupcakes on the shelves one by one. I define the sizes by the cupcake's bottom and top diameter:

• Mini: bottom diameter 3/4" (1.9 cm), top diameter 1-1/4" (3.2 cm)
• Standard: bottom diameter 2" (5.1 cm), top diameter 2-1/2" (6.4 cm)
• Large: bottom diameter 2" (5.1 cm), top diameter 3" (7.6 cm)

You can measure your own cupcake together with its liner to see which size it falls into. The figures are approximate; the count changes with the diameter of the paper liner and how tightly you space them. For a combined layout, multiply each unit's figure by the number of that unit you use and add them up: for the L layout in the package, add the figure for the straight unit and the figure for the corner unit; for the U layout, add twice the corner unit's figure to the straight unit's figure.

As a sales display: This stand was designed for product display as much as for cupcakes. At a fair, market, or craft stall you can arrange small items such as jewelry, small gifts, and handmade soap and candles tier by tier, together with counter items such as business cards and price tags. The modular structure is most useful here: you can set up one, two, or three units to suit the length of your counter and grow the display; the U layout wraps the front counter of a small market booth with tiers of products on three sides. Because each tier sits behind the one before it, the items in the back rows are visible from the front too. The 5" (12.7 cm) of clear height between the tiers is comfortable for small items; put a taller piece on the open top shelf. I designed the shelves for light items; don't put bottles, full bowls, or heavy decor objects on them.

Tier height: The 5" (12.7 cm) of clear height between the tiers is generous for cupcakes: even a large cupcake that rises to 3-1/2" (8.9 cm) with its frosting leaves about 1-1/2" (3.8 cm) of clearance under the shelf above. Moreover, the upper shelf covers only the back 1-3/8"–1-7/8" (3.5–4.8 cm) band of the shelf below; the rest of that shelf is completely open on top. The shelf width is 6" (15.2 cm); standard and large cupcakes can be arranged in two rows on a shelf.

My layout suggestions:

• Give the fullest arrangement to the lower tiers. Keeping the weight low also helps the balance of each unit.
• Account for where the shelf holders are. On the straight unit 3" (7.6 cm) in from the shelf ends, and on the corner unit 3-1/2" (8.9 cm) in from the arm ends, the holder plate, 1/2" (12.7 mm) thick, rises from the back 2"–2-1/2" (5.1–6.4 cm) of the shelf upward. Arrange the rows in front of and on either side of this thin plate; no cupcake goes on top of it.
• Put your showpieces in the corner. The corner area where the two arms of the L shelves meet is unobstructed, and in the L and U layouts it's the spot that catches the eye most from the front. The top shelves, which are completely open on top, are also for products with name decorations, candles, or whatever you most want to draw attention to.
• Reserve the shelf and arm ends for light pieces. Don't put anything heavy on the ends that lie outside the holders.
• Don't put cupcakes directly on the wood surface; arrange them in their paper liners or on coasters (details in the Paint, Varnish and Food Contact block).

3 CNC files in SVG, DXF, and DWG format: I provide the same cut package in three formats; whichever CAD or CNC program you work with, there's a format in the package that you can open. Each file contains two separate 24" × 48" (61 × 122 cm) sheet areas: the five parts of the straight unit are laid out in one and the five parts of the corner unit in the other; 10 parts in total. You don't need paid software to inspect the files: LibreCAD (free, open-source) and QCAD (free community edition), both of which run on Windows and Mac, are enough; if you want a Windows-only option, Autodesk's free viewer DWG TrueView is available. If you're having the parts CNC- or laser-cut, you don't have to open the file yourself; you can hand it straight to the shop.

2 PDF guides (imperial and metric): I provide the same guide as two separate files, one with inch measurements and one with millimeters; print whichever system you work in. The guides are in English and explained through drawings; the imperial guide is 12 pages. The first two pages are the welcome letter and the license; after that comes a separate section for each of the two units. Each section includes a perspective diagram showing the parts by number, dimensioned front and side views, a dimensioned top view of the shelves, a dimensioned drawing of the shelf holder, and a materials page.

I prepared the guide for A3; you can also print it scaled down to A4 or US Letter. Since every dimension is written out in numbers on the page, and the guide has no 1:1 scale template, scaling down doesn't spoil any measurement.

The guide has no separate assembly page, because this stand has no assembly in the traditional sense: once the parts are cut, they fit together in seconds through the interlocking system. I've described the fitting sequence for the two units separately in the Assembly section, and how to set the units up side by side in the Combining and Layout Plan block. The guide also has no cut list table or sheet layout page; the layout is in the CNC file itself, and the full list of the 10 parts is in the Panel Count and Cut List block in the Materials section. There's no printable template for hand-cutting on this project either: if you're cutting with a jigsaw, you mark the dimensions from the guide onto the sheet (Two Build Options block).

What decides your material on this project isn't the wood species but the thickness. I drew the slots in the shelf holders and the notches in the shelves 1/2" (12.7 mm) wide on both units; the design was prepared for plywood labeled 1/2". If the sheet is thicker than this width, the shelves won't go into the slot; if it's much thinner, they sit loose in the slot.

Nominal versus actual thickness: The thickness on a plywood label and the sheet's actual thickness are often different. The sheet I used as the reference on the guide's materials page is sold in the US under a "1/2 inch" label, but its actual thickness is about 0.453" (11.5 mm). With this sheet, about 1.2 mm of clearance is left in every joint, and the shelves go into their slots without being forced. Trust the measurement, not the label: measure the sheet with calipers at several points before you buy it.

In my own build: I built both units to the guide's dimensions with a panel labeled 1/2"; the parts seated in the slots, and no adjustment was needed in the file or the slots.

Recommended: plywood labeled 1/2" (12.7 mm) or 12 mm, measuring 11.5–12.7 mm in actual thickness. I recommend two product groups:

• Prefinished maple plywood — This is the product I used as the reference on the guide's materials page: Columbia Forest Products PureBond Prefinished Maple Project Panel, 1/2" × 2 × 4 ft (12.7 mm × 61 × 122 cm). It's a hardwood plywood made for interior use, with a maple veneer face; it's sold with the surface sanded and coated with a clear protective layer. Since it needs no paint or varnish, it's my first choice for this stand.
• Birch plywood — Its plies are tight and free of gaps, so the cut edge comes out clean. Where plywood is sold by millimeter thickness (Europe and elsewhere), look for a sheet labeled 12 mm, and be sure to measure its actual thickness. If the sheet is uncoated, you'll need to protect its surface yourself (Paint, Varnish and Food Contact block).

I recommend buying both sheets from the same product. Because the units stand side by side, a difference in color and texture is immediately noticeable; the same product makes the two units look like a whole.

Avoid:

• A sheet with an actual thickness above 12.7 mm, for example plywood labeled 5/8" (15.9 mm). The shelves won't go into the slots; the thin section beside a forced slot can crack.
• A sheet with an actual thickness of 10 mm or less, for example plywood labeled 3/8" (9.5 mm). The shelves sit loose in the slots with a gap of about 3 mm; on this stand it's the fit of the joint itself, not glue, that holds the shelves, so the shelves play and don't sit level.

In the guide I wrote that sheets between 3/8" and 5/8" (9.5–15.9 mm) can also be used; that holds on condition that the slots are redrawn to suit the sheet. If you want to use the file as it is, stay within the recommended range above.

If the thickness you measure falls outside the 11.5–12.7 mm range, message me on Etsy before you start cutting. It's possible to redraw the slots to suit your sheet; let's adapt the file together.

2 sheets for the package: each unit comes out of its own 2×4 ft (61 × 122 cm) sheet. The cut file has two separate 24" × 48" (61 × 122 cm) sheet areas: the five parts of the straight unit in one and the five parts of the corner unit in the other. For the U layout, if you have the corner unit's sheet cut twice, you need 3 sheets in total. If you buy a 4×8 ft (122 × 244 cm) sheet, the parts of four units come out of it; if you're thinking of building a larger layout, this is the most economical way.

The shelves of the straight unit are 25" (63.5 cm), while the short edge of the sheet is 24" (61 cm). That's why the straight unit's shelves are laid out along the sheet's 48" (122 cm) long edge; no other layout is possible. The L shelves of the corner unit, on the other hand, are nested with their arms interlocking. About half of each sheet turns into parts, with the remaining area in narrow strips: a wrongly cut shelf or holder can't be recut from these offcuts. If you're cutting by hand, I recommend keeping a spare piece of sheet on hand.

The 10 parts in the cut file (all the thickness of the sheet):

Straight unit sheet (5 parts)

• Shelf (3 pieces): 25" × 6" (63.5 × 15.2 cm), with corners rounded to a 1/2" (12.7 mm) radius. On the back edge there are two open notches that fit onto the shelf holders. The three shelves look very much alike, but each has its own tier; they're numbered 1 to 3 in the guide.
• Shelf holder (2 pieces): 17-1/8" × 14-1/2" (43.5 × 36.8 cm), a plate in the shape of a "Λ" when seen from the side. Its vertical back leg and sloped front leg are 2-1/2" (6.4 cm) wide; the gap between the two legs rises to a height of 10-1/4" (26.0 cm) above the table. Its sloped edge makes a 40° angle with the vertical, and on this edge there are three horizontal slots into which the three shelves fit.

Corner unit sheet (5 parts)

• 1st shelf (1 piece): L, side length 19-3/4" (50.2 cm), arm width 6" (15.2 cm). On the inner edge of its two arms, one notch each that fits onto the shelf holders.
• 2nd shelf (1 piece): L, side length 15-1/8" (38.4 cm), arm width 6" (15.2 cm). One notch each in the same position.
• 3rd shelf (1 piece): L, side length 11" (27.9 cm), arm width 6" (15.2 cm). One notch each in the same position.
• Shelf holder (2 pieces): The same dimensions as the straight unit's shelf holder.

The outside corner of the L shelves is rounded to a 2" (5.1 cm) radius, and their other corners and the corners of the holders to a 1/2" (1.3 cm) radius. The four shelf holders were drawn to the same dimensions; they aren't divided into right and left.

Mark the shelves in pencil the moment you cut them. The three shelves of the straight unit are the same size and look very much alike; if you set them aside without telling them apart, it's easy to mix them up later. How to tell them apart and mark them is covered in the Identifying and Marking the Parts block.

No glue, nails, or screws. I designed this stand to be used glue-free, to be taken apart and set up again. The ten parts are joined to one another only by halving joints: the notch on the back edge of the shelf fits onto the shelf holder, and the holder's slot fits onto the shelf, and the two parts grip each other. These joints both carry the load and hold the shelves in place. There's no connecting part between the units either; each unit stands on its own joints.

Why glue-free: This is where a modular system really pays off. Units that come apart are carried and stored as a flat package and can be set up in a different layout at every event: a single straight unit one day, a U layout another. No tools are needed for setup; the moment the shelves are seated in their slots the unit is ready to use, with no clamps and no drying time to wait out.

Optional glue: If you want to use a unit as a solid, single-piece structure that can't be taken apart, you can apply wood glue to the joint surfaces; in that case the parts can't be taken apart again.

Don't drive nails or screws into the shelf holders or into the area around the notches of the shelves. The thin sections beside the slots can crack at the edge; and a unit that's been nailed or screwed can no longer be taken apart.

Consumables: To clean up the edges and notch mouths after cutting, 180–220 grit sandpaper, a flat sanding block, and a pencil for marking the shelves are enough.

This is a tabletop stand designed for indoor use. Since the reference sheet is sold prefinished, paint or varnish isn't required; after cutting, the units are ready to use.

Cut edges: The prefinished coating is only on the faces of the sheet. On the cut edges the plywood's layer lines are left exposed, as bare wood. You can leave the edges in their natural state, or brush just a thin coat of water-based varnish onto the edges alone (Sanding and Edge Finishing block).

If you still want to paint: Paint may not grip a prefinished surface well directly. Dull the surface with 220 grit sandpaper, then apply a bonding primer and a water-based acrylic furniture paint (acrylic enamel, cabinet paint). If you used an uncoated sheet such as birch, water-based polyurethane varnish protects pale wood without yellowing it; two thin coats in a matte or satin sheen are enough. Because the units will stand side by side, finish all of them with the same product and the same number of coats; otherwise a difference in tone will stand out at the line where they meet.

Don't paint the slots or the notches. Every coat of paint narrows the clearance in the slot; and each time the units are set up and taken apart, the paint at the slot mouth rubs and wears away. Before painting, cover these areas with masking tape, paint while the parts are separate, and remove the tape after the paint has dried.

Food contact: I'm not making a firm ruling on whether the wood, the sheet's prefinished coating, or a product you apply afterward is suitable for direct contact with food. Here is what I recommend:

• Arrange cupcakes in their paper liners or on coasters; don't put frosted items directly on the wood surface.
• If you're going to apply paint or varnish, choose a product that is labeled as suitable for food contact ("food safe" or "food contact").
• Don't settle for the surface feeling dry to the touch; wait for the full cure time stated on the label, and only then use the stand with food.

The same principle applies at a sales display: display items that could leave a mark, such as candles, soap, or oily cosmetics, on a coaster or a small tray; uncoated cut edges soak up a stain more easily than the surface.

There are two ways to build this project, and which one you choose depends on what you have access to.

1. CNC / laser cutting — You hand the SVG, DXF, or DWG file from the package to a CNC or laser shop. The file has two sheets; the shop cuts one sheet for each unit. All ten parts come out with the same precision; the sloped edges of the shelf holders and the notches and slots, 1/2" (12.7 mm) wide, in particular are cut to the most accurate dimensions this way. If you're having it laser-cut, ask the shop beforehand whether its machine can cut 12 mm plywood cleanly.
2. Cutting by hand with a jigsaw — You draw the dimensions from the guide and from the cut list on this page onto the sheet yourself and cut them out. The shelves are easy: rectangles with straight edges on the straight unit, and L's with all edges straight on the corner unit; the only curves are the corner roundings.

I recommend CNC or laser cutting for the shelf holders. The holder has two sloped edges, the gap between the two legs, and three narrow slots. The sloped edge makes a 40° angle with the vertical; a small angle error shifts the position of all three slots, and the shelves don't sit level. This project has one more problem: if the four holders don't come out exactly identical, the tiers of the straight unit and the corner unit won't meet at the same alignment when they come together side by side. As a middle path, you can have the four holders cut at a shop and cut the shelves yourself.

Four notes if you're cutting by hand:

• Long straight cuts: Cut the 25" (63.5 cm) shelf edges and the arms of the L shelves by running the jigsaw against a straightedge batten. If the arm width varies from one end to the other, or if a shelf edge comes out wavy, the edges won't line up when the two units come together side by side.
• Outside corner: Draw the rounded outside corner of the L shelves with a 2" (5.1 cm) radius; a compass or the rim of a 4" (10.2 cm) diameter container will do the job. Round the other corners with a 1/2" (1.3 cm) radius; you can also cut them square first and round them afterward with sandpaper.
• Notches and slots: Cut the two sides parallel up to the line, cut out the piece between at its base, and true the base with a file. Cut on the inside of the line and sneak up on the final size by sanding, test-fitting with a shelf; in a notch 1/2" (12.7 mm) wide, material that's been removed doesn't come back.
• If you cut the holder by hand anyway: Cut and true one first, then draw the remaining three using it as a template; transfer the angle to the sheet with a protractor.

Mark each shelf the moment you cut it; I explained why in the Identifying and Marking the Parts block.

The four topics below are the ones that are hard to fix once the parts are cut. Read them before you start cutting, before you send the file to a shop.

1. Measure your sheets before cutting. The slots and notches were drawn for 1/2" (12.7 mm) plywood. If you're taking your own sheets to the shop, measure the thickness of both sheets with calipers and make sure it falls within the 11.5–12.7 mm range; if you'll use the shop's sheets, tell them the thickness explicitly. What happens with thicker and thinner sheets is covered in the Material Choice and Panel Thickness block.

2. Leave the kerf allowance on the correct side. A router bit or a laser beam removes some material over the line. This project has no inner contour: the notches, the slots, and the gap between the holder's two legs are also part of the part's outer line. Remind the shop that all the parts must be cut on the outside of the line; a slot cut from the wrong side grows and the shelf sits loose in the slot.

3. Don't change the layout. The straight unit's shelves are 25" (63.5 cm), and the short edge of the sheet is 24" (61 cm). If the shop will rearrange the parts with its own layout software, tell them these shelves must stay parallel to the sheet's 48" (122 cm) edge.

4. Keep the parts separate, unit by unit. Ask the shop to package the parts of the two sheets separately; since the straight unit's shelves look very much alike, this separation makes your job easier at setup. Have the CNC file cut as it is, without editing it; if you'll have the corner unit's sheet cut twice for the U layout, say so up front too. Beyond that there's no extra work: there are no miter cuts, holes, or nail positions; ask the shop only to cut the contours in the file.

The 10 parts of the package are easy to tell apart. The four shelf holders are identical; there's no right or left among them, and it makes no difference which holder you put on which unit.

Identifying the shelves:

• Corner unit: The L shelves tell apart by their size: the largest L, 19-3/4" (50.2 cm), goes at the bottom, the middle L, 15-1/8" (38.4 cm), in the middle, and the smallest L, 11" (27.9 cm), at the top.
• Straight unit: All three shelves are 25" × 6" (63.5 × 15.2 cm) and look very much alike, but each has its own tier. Place them according to the part numbers in the guide, and try each shelf in its slots before fitting it. If a shelf doesn't seat fully in its slots, or doesn't line up with the shelf on the same tier of the adjacent corner unit, swap it with another shelf and try again.

Once the shelves are on their correct tiers, write a letter and a tier number on their undersides in pencil: S1, S2, S3 for the straight unit and C1, C2, C3 for the corner unit. At the next setup you'll find the right order without searching.

Don't take the straight unit apart after the first setup without marking its shelves. Once placed side by side they're hard to tell apart; if an unmarked shelf is fitted on the wrong tier, the shelves of the straight unit and the corner unit won't meet at the same alignment.

Slot check: At the first setup, fit each shelf into its own slots once and take it out again. The shelf should go in all the way by hand, without being forced, and sit level. On a sheet labeled 1/2" (12.7 mm), a slight clearance in the joint is normal; the design was prepared for that clearance. Lightly sand a notch that feels tight on its inside edge with a flat block and try again; don't force the shelf in with a mallet.

Apply the sandpaper only to the cut edge of the notch. If it touches the shelf's prefinished face, the coating gets scratched and that area goes dull; and in a notch that's opened too much, the shelf sits loose.

There's no assembly in the traditional sense on this stand: once the parts are cut and prepared, they fit together in seconds through the interlocking system. No tools, glue, or waiting are needed; all you need is a flat surface and marked shelves.

1. Set the shelf holders in place — One after the other, stand the two holders upright on a flat surface with their sloped edges facing forward and about 18" (45.7 cm) between them.
2. Start with the bottom shelf — It's easiest to fit the shelves from bottom to top. Seat the S1 shelf so that the notches on its back edge land on the bottom slots of the holders. The first shelf to seat keeps the two holders at the correct spacing; the shelves above find their slots easily.
3. Middle and top shelf — Fit the S2 shelf into the middle slots and the S3 shelf into the top slots.
4. Check — The shelves should sit level, and the two ends of the shelves should extend an equal 3" (7.6 cm) outside the holders. The bottom shelf projecting slightly in front of the holders' feet is by design; don't mistake it for misalignment.

Disassembly: The reverse of fitting. Take the shelves out of their slots one at a time, starting from the top, then lay the holders down and pack the five parts flat, stacked.

Don't force the shelves at an angle when fitting and removing them. Prying a shelf at one end can crush the slot edges; a crushed slot widens over time and the shelf starts to wobble. Hold the shelf equally at both ends and move it straight.

The corner unit is set up on the same logic, in seconds; the only difference is that the two holders stand at right angles to each other.

1. Set the holders in place — One after the other, stand the two holders on a flat surface at right angles to each other: each goes under one arm of the L, 3-1/2" (8.9 cm) in from the arm end. The vertical back edge of the holders should face the corner, that is, the inside gap; the sloped edge with the slots should face outward.
2. Start with the bottom shelf — Seat the C1 shelf so that the notches on its two arms land on the bottom slots of the two holders. This shelf keeps the two holders at the correct angle and spacing.
3. Middle and top shelf — In the same way, fit the C2 shelf into the middle slots and the smallest, C3 shelf into the top slots.
4. Check — The shelves should be level; the arm ends of the three shelves should finish in the same alignment on both sides, and the holders should sit 3-1/2" (8.9 cm) in from the end on each arm.

Bringing the units side by side: First set up each unit separately in its own spot, then bring them closer.

• Position: Bring the corner unit up so that one of its arm ends touches the shelf end of the straight unit. There's no right or left version of the corner unit; turn it to suit whichever end of the straight unit it goes on.
• Alignment: The front and back edges of the two shelves should be on the same line on all three tiers. If the edges are out of line, correct it without lifting the unit, by pushing it gently at its base.
• U layout: Bring the second corner unit up to the other end of the straight unit in the same way.

Since the units aren't connected to each other, that's all there is to placing them; you don't fit any part between them. To change the layout or put it away, it's enough to pull the units apart one by one.

Disassembly: In reverse order: take the C3 shelf out of its slots first, then the C2 and C1 shelves, then lay the holders down.

Don't drag the units by their shelves. A shelf that sits glue-free can slip out of its slot; when correcting the alignment, push the unit from the lower part of its holders.

Don't sand the prefinished surface all over. The faces of the reference sheet are prefinished; sanding all over takes off this protective layer and dulls the surface. Use the sandpaper on the edges and at the points that feel tight during the slot check.

Ease the edges lightly: After cutting and before the first setup, soften the front edges of the shelves and the shelf and arm ends with 180–220 grit sandpaper in a pass or two; clean up the sloped front edge of the shelf holders the same way. That way the plywood edge splinters less, and cupcake liners, product packaging, and hands don't catch on the edge. The 2" (5.1 cm) radius outside corner of the L shelves and the 1/2" (1.3 cm) radius corners of all the shelves are already cut rounded; with sandpaper, just take off the cut marks. Take off any fine burrs left over from CNC cutting at this stage too.

Don't over-round the ends where the units meet. The sharper the line where the straight unit's shelf ends and the corner unit's arm ends meet when they come together side by side, the more uninterrupted the row looks; on these ends, just take off the burr.

Don't round over the insides of the notches and slots. These are the surfaces that hold the shelves in place at every setup; in a slot whose mouth has been rounded, the shelf plays. Here, use sandpaper only at the point that felt tight during the slot check, with a flat block and a little at a time.

Edge appearance: The layer lines on the cut edge stay exposed. You can leave them natural; if you want a more protected edge, brush a thin coat of water-based varnish onto the edges and protect the notch and slot edges with tape. The sequence I recommend: cut → mark → sand the edges → slot check → (optional) edge varnish → set up.

This stand's stability comes from its geometry. The guide doesn't give a load limit, so I'm not writing you a carrying capacity in kilograms; instead I'll explain how the units stay balanced and what you should watch for.

Each unit stands on its own base. The base of the shelf holders that sits on the table is 14-1/2" (36.8 cm) long, while the units are 17-1/8" (43.5 cm) tall. Because the upper tiers step back, the weight of the shelves and what's on them bears on the rear part of the base; on the straight unit the bottom shelf extends only about 5/16" (0.8 cm) in front of the holders' feet. On the corner unit, the two holders at right angles give their base against sway, one in one direction and the other in the perpendicular direction. When I put products on the shelves of the corner unit in my own build, the corner included, the unit held its balance.

Even so, here is what you should watch for:

• A flat, solid surface: Because each unit rests on two thin bases, a thick, soft tablecloth or a folded piece of fabric can sink one of the bases, and the shelves lean; the shelves of units standing side by side also go out of alignment. If you use a cloth, make it flat and taut.
• Light items, weight low: I designed the shelves for light sweets and small sales items such as jewelry and small gifts; don't put bottles, full bowls, or heavy decor objects on them. Place the relatively heavy pieces on the lower tier and close to the holders, and don't put anything heavy on the shelf and arm ends.
• Away from the table edge: Don't place the units at a table edge where guests, or customers in front of the counter, might bump them as they pass; set them at least a hand's width in from the edge.
• With more than one unit: Because the units aren't connected to one another, each carries its own balance. Put the weight on the lower tiers of each unit separately, and check the alignment of the units during the day.
• Children: The lower tiers are at a height small children can reach, and the shelves weren't designed for climbing or hanging on. At an event with a lot of children, keep the stand in your sight.
• Don't carry it loaded: Because the shelves sit glue-free, a shelf can slip out of its slot when the unit is lifted. Set the units up in place empty, then arrange the cupcakes and products where they stand.

Transport: I designed the units to be taken apart and set up again. When the package is taken apart, it breaks down into 10 flat parts; by my calculation, stacked together in a single pile they make a package of about 25" × 19-3/4" × 5" (63.5 × 50.2 × 12.7 cm). If you want to pack the units separately, the straight unit takes up about 25" × 17-1/8" × 2-1/2" (63.5 × 43.5 × 6.4 cm) and the corner unit about 19-3/4" × 19-3/4" × 2-1/2" (50.2 × 50.2 × 6.4 cm). You can carry them this way, in a thin box or bag, to a fair, a market stall, or a celebration and set them up on site. When stacking the parts, put a cloth or cardboard between them so the prefinished faces don't scratch one another.

Disassembly: First separate the units from each other, then take each one apart starting from the top shelf (Straight Unit Assembly and Corner Unit Assembly and Combining blocks). Since setup takes seconds, when you move the units I recommend taking them apart rather than carrying them set up. If you do need to carry one set up, carry it empty and lift it gripping the holders by their lower parts with both hands; don't lift it by the shelves, because a glue-free shelf can slip out of its slot.

Cleaning: Wipe with a damp, well-wrung cloth, then dry with a dry cloth. Don't soak the parts in water, wash them under the tap, or put them in the dishwasher; plywood doesn't tolerate staying wet for long, and the plies can swell and the slots can lose their shape. Wipe off frosting or sugar stains before they dry; the uncoated cut edges soak up a stain more easily than the surface.

Storage: Store the disassembled parts in a dry place, away from heat sources such as a radiator or direct sunlight, stacked flat on a level surface; thin plywood can warp if left leaning at an angle for a long time. Thanks to the S and C marks under the shelves, you can tell the parts apart at the next setup without searching. Keep them under a cover or in a box so they don't collect dust.

This stand is a load-bearing structure, so changing the size isn't just a matter of scaling the file up or down. Rescaling the CNC files in CAD software is technically possible, but the slots in the shelf holders and the notches in the shelves were designed for 1/2" (12.7 mm) plywood. If you scale the file up or down proportionally, those slots change too, but your sheet's thickness stays the same; the shelves either sit loose in the slot or won't go into it. If you scale only one unit, the tiers of the straight unit and the corner unit also no longer meet at the same height and the same alignment. If you want a different size, message me on Etsy before changing the scale; let's work out together which measurements need to stay fixed.

Yes — this is a standard, platform-wide Etsy feature. The download link doesn't expire; you can re-access your files anytime from the "Purchases and Reviews" page in your Etsy account, with no limit on how many times you download.

Of course — I make every plan myself, and you're welcome to reach out to me directly through Etsy with any question, before or after your purchase. I stand behind every design I share.

No — these files are for personal use only. Selling what you make from them, or using the design or files for any other commercial purpose, isn't included in this purchase.

I don't offer refunds once the files have been downloaded — this is standard practice given the nature of digital goods. That said, if you run into an actual problem with the files (won't open, something's missing), reach out and I'll help sort it out.

I recommend a sheet labeled 1/2" (12.7 mm) or 12 mm, measuring 11.5–12.7 mm in actual thickness. The slots in the shelf holders and the notches in the shelves were drawn 1/2" (12.7 mm) wide; in my own build I made both units with a panel labeled 1/2" and the parts seated in place. Avoid a sheet whose actual thickness exceeds 12.7 mm, for example 5/8" (15.9 mm) plywood: the shelves won't go into the slots. Avoid 10 mm and under as well, for example 3/8" (9.5 mm) plywood: the shelves sit loose in the slots; because the stand is glue-free, this gap lets the shelves play. The 3/8"–5/8" (9.5–15.9 mm) range in the guide holds on condition that the slots are redrawn to suit the sheet. Measure both of your sheets with calipers and, after cutting, fit each shelf into its slot once to test it. If the thickness you measure falls outside the 11.5–12.7 mm range, message me on Etsy before you start cutting; let's adapt the file together.

When filled with a single size of cupcake, the straight unit holds about 260 mini, 60 standard, or 45 large cupcakes; the corner unit holds about 250 mini, 55 standard, or 40 large cupcakes. I calculated these figures by placing the cupcakes one by one according to the shelf dimensions. I define the sizes by bottom and top diameter: mini 3/4" (1.9 cm) bottom, 1-1/4" (3.2 cm) top; standard 2" (5.1 cm) bottom, 2-1/2" (6.4 cm) top; large 2" (5.1 cm) bottom, 3" (7.6 cm) top. The count varies with the diameter of the cupcake liner and how closely you space them. In a combined layout, multiply each unit's figure by the number of that unit you use and add them up; for the U layout, add twice the corner unit's figure to the straight unit's figure. The 5" (12.7 cm) of clear height between the tiers is also enough for large cupcakes with tall frosting. The same shelves can also be used to display small items at a sales stall. Details are in the Capacity and Layout block.

Yes. I designed this stand to be multi-purpose: alongside cupcakes and light sweets, it also works as a display stand at a fair, market, or craft stall for jewelry, small gifts, small handmade items, and counter items such as business cards and price tags. The modular structure fits your counter: a single straight unit suits a short counter, the straight unit plus the corner unit makes a display that turns from the front of the counter to its side, and the U layout becomes a small market stall that shows the products from three directions. Because each tier sits behind the one before it, the items in the back rows are visible from the front too; there's 5" (12.7 cm) of clear height between the tiers, and taller pieces go on the open top shelf. The shelves are for light items; don't put bottles or heavy objects on them. Details are in the Capacity and Layout block.

I don't recommend it. I'm not making a firm ruling on direct food contact with the wood, with the sheet's prefinished coating, or with the paint or varnish you put on afterward; the safest way is to arrange the cupcakes in their paper liners or on coasters. If you're going to paint or varnish, choose a product whose label says it's suitable for food contact, and wait for the full cure time stated on the label. Details are in the Paint, Varnish and Food Contact block.

The units aren't connected to one another; there's no screw, clamp, or connecting part between them. Each unit stands on its own and you bring them side by side: when you touch the arm end of the corner unit to the shelf end of the straight unit, the shelves continue in the same alignment on all three tiers, because the shelf width, tier heights, and steps are the same. The cut file in the package contains one straight unit and one corner unit; together they set up an L layout of about 44-3/4" × 19-3/4" (113.7 × 50.2 cm). For the U layout this project takes its name from, a corner unit goes at each end of the straight unit: you have the corner unit's sheet cut twice, 3 sheets in total, and about 64-1/2" × 19-3/4" (163.8 × 50.2 cm). With four corner units and two straight units you can also set up a ring seen from four directions, and with straight units a long row or a back-to-back island. I give the capacity per unit; in a combined layout, multiply by the number of units and add them up. Details are in the Combining and Layout Plan block.

Glue isn't needed; I designed this stand to be used glue-free. The shelves sit in the shelf holders' slots by the interlocking fit alone, and there are no nails or screws either. Each unit sets up in seconds and comes apart into five flat parts; when the package's 10 parts are stacked, they make a package of about 25" × 19-3/4" × 5" (63.5 × 50.2 × 12.7 cm). You can take it as a flat package to a fair, a market stall, or a celebration and set it up in that day's layout. If you want to use a unit as a solid, non-removable single piece, you can apply wood glue to the joints, but then it can't be taken apart again. Details are in the Joinery: No Glue Needed and Disassembly, Transport and Storage blocks.
