Learning how to build an acrylic display case is a great project if you have a collectible, model, piece of memorabilia, or product that doesn't fit inside a standard enclosure.
At its simplest, an acrylic display case is just a group of precisely cut clear acrylic panels joined together to form a box.
The concept is simple.
Getting all six panels square, clear, and properly fitted is where things become more interesting.
In this guide, we'll walk through the entire process—from measuring your item and choosing acrylic thickness to cutting the panels, assembling the case, and avoiding some of the most common DIY mistakes.
And if you get halfway through the planning stage and decide you'd rather have someone else cut the panels, we'll cover that option too.
What Do You Need to Build an Acrylic Display Case?
For a basic DIY acrylic display case, you'll generally need:
- Clear acrylic sheet
- Measuring tape or ruler
- Square
- Fine-tip marker or removable marking method
- Acrylic cutting tool, saw, or access to a laser cutter
- Fine sandpaper or finishing tools
- Acrylic solvent cement or another acrylic-compatible adhesive
- Fine applicator bottle or syringe for solvent cement
- Right-angle blocks or corner jig
- Clamps or masking tape
- Clean microfiber cloth
- Flat work surface
- Appropriate eye and hand protection
The exact tools depend on how you plan to cut the acrylic.
A small DIY case made from relatively thin acrylic can sometimes be produced using basic tools.
For thicker acrylic, larger cases, or projects where you want extremely accurate parts, power tools or laser-cut panels can make the process significantly easier.
Step 1: Decide What You Are Displaying
Before cutting anything, start with the object.
Place the collectible exactly how you intend to display it.
That might be:
- A Pokémon booster box
- An Elite Trainer Box
- A LEGO model
- A sports collectible
- A signed item
- An action figure
- A statue
- A model car
- A vintage toy
- An award
- A retail product
- A piece of memorabilia
The object determines the case—not the other way around.
This is one of the biggest advantages of building a custom acrylic display case.
You aren't forced to find a collectible that fits a predetermined box.
You can build the box around the collectible.
Step 2: Measure the Item
Measure the object's maximum:
Width × Height × Depth
Measure the widest, tallest, and deepest parts of the entire display.
Don't forget anything that extends beyond the main object.
That can include:
- Packaging tabs
- Handles
- Protective wrapping
- Display stands
- Bases
- Accessories
- Mounting hardware
- Cables
Write the measurements down.
Then measure them again.
A small measurement error can become a big problem after six acrylic panels have already been cut.
Don't Make the Inside Exactly the Same Size as the Object
Your display needs some clearance.
If an item measures exactly 8 inches wide, an interior width of exactly 8 inches leaves essentially no room to insert it comfortably.
How much space you add depends on the look you want.
A fitted collectible case may only need a relatively small amount of working room.
A decorative display with figures, lighting, stands, or multiple objects may look better with considerably more space around the subject.
The important thing is to decide on the inside dimensions first.
Then design the acrylic panels around those dimensions.
Step 3: Choose Your Acrylic Thickness
Acrylic thickness affects more than durability.
It also affects:
- Weight
- Rigidity
- Edge appearance
- Panel dimensions
- Joint design
- Material cost
- Overall appearance
For many smaller DIY display cases, acrylic around 3mm thick is a practical starting point.
At Aegis Acrylic, our comparable option is called Shield 3mm.
For larger displays or cases where you want a heavier, more substantial appearance, thicker acrylic may make more sense.
Our premium Aegis option uses 6mm acrylic.
Remember that acrylic thickness becomes part of your panel calculations.
If one panel sits between two other panels, the thickness of those surrounding panels affects its final dimensions.
That brings us to the part of acrylic fabrication that causes quite a few DIY headaches.
Step 4: Plan How the Panels Will Overlap
Before calculating your cut sizes, decide how the panels will meet.
There is more than one correct way to build an acrylic box.
For example, you might build a five-sided cover consisting of:
- Front
- Back
- Left side
- Right side
- Top
The cover can then sit over a separate acrylic, wood, or decorative base.
This is a particularly useful design for collectibles because you can simply lift the acrylic cover to access the item.
Another option is a fully enclosed six-sided box with a removable lid.
Whatever design you choose, determine which panels overlap the others before you cut anything.
Understanding Panel Dimensions
Let's say you want your front and back panels to run the full outside width of the case.
Your side panels sit between them.
In that design:
Front and back: Full case width
Side panels: Case depth minus the thickness of the front and back panels
If you're using 3mm acrylic:
Side Panel Depth = Outside Depth - 6mm
Why?
Because you have:
3mm front panel + side panel + 3mm back panel.
Change the joint design and the calculations change too.
This is why simply cutting six rectangles using the same three box dimensions doesn't work.
Always sketch the construction first.
Even a basic drawing showing which panel sits inside which other panel can prevent an expensive mistake.
Step 5: Create Your Cut List
Once you know the finished dimensions and overlap method, create a cut list.
For example:
| Panel | Quantity | Width | Height |
|---|---|---|---|
| Front | 1 | ___ | ___ |
| Back | 1 | ___ | ___ |
| Left Side | 1 | ___ | ___ |
| Right Side | 1 | ___ | ___ |
| Top | 1 | ___ | ___ |
| Base | Optional | ___ | ___ |
Fill in every measurement before starting.
Then verify the math.
This is one of those projects where spending an extra five minutes checking measurements can save an entire sheet of acrylic.
Step 6: Cut the Acrylic Panels
There are several ways acrylic can be cut.
The right method depends on the thickness, equipment available, and the quality of finish you're trying to achieve.
Score and Snap
Some thinner acrylic sheet can be scored repeatedly along a straight line and snapped along the score.
This method can work for simple rectangular DIY projects.
However, it becomes increasingly difficult when you need complex shapes or extremely precise dimensions.
Saw Cutting
A table saw, circular saw, or similar equipment can cut acrylic when used with the appropriate blade and technique.
If you're using power tools, follow the tool and acrylic manufacturer's safety recommendations.
Secure the material properly and don't attempt cuts you're uncomfortable making.
Laser Cutting
A CO2 laser can produce extremely precise acrylic parts and is particularly useful when the design includes:
- Rounded corners
- Slots
- Tabs
- Holes
- Engraving
- Unusual shapes
- Multiple identical components
This is the primary method we use at Aegis Acrylic.
If you already have an SVG, DXF, AI, or PDF design, you can also request custom acrylic laser cutting from Aegis Acrylic.
Step 7: Keep the Protective Film On
Most acrylic sheets arrive with protective masking or film.
Leave as much of that protection in place as possible while you're cutting, handling, and test-fitting the panels.
It protects the visible surfaces from scratches while you're working.
When you're ready to bond a joint, remove enough protective material from that edge to expose the acrylic.
You don't need to immediately uncover the entire panel.
That protective layer is your friend during fabrication.
Step 8: Check and Finish the Edges
The quality of the edges has a major effect on the appearance of the finished case.
Check each panel for:
- Chips
- Uneven edges
- Burrs
- Saw marks
- Incorrect dimensions
- Out-of-square cuts
If you're mechanically finishing an edge, work carefully.
The goal is a clean, straight mating surface.
Don't aggressively round the edges that will eventually become bonded joints.
Those surfaces need to meet each other properly.
Step 9: Dry Fit the Entire Display Case
This may be the most important step in the entire project.
Do not start gluing immediately.
First assemble the entire case without adhesive.
Use:
- Masking tape
- Corner blocks
- Right-angle jigs
- Light clamps
Check every corner.
Does the top sit flat?
Are the sides square?
Do the front and back line up?
Does one panel extend past another?
Does the case rock when sitting on a flat surface?
If something doesn't fit now, fix it now.
Once solvent cement has been applied, your options become much more limited.
Step 10: Prepare a Flat Assembly Surface
Acrylic boxes amplify small alignment errors.
If your work surface isn't flat, your finished case may not be square.
Use a clean, level surface.
A right-angle jig is extremely useful.
You can use commercial corner jigs or create simple square blocks that hold two panels at 90 degrees while they are being joined.
The goal is to prevent the panels from moving while the joint forms.
Step 11: Join the Acrylic Panels
One common method for permanently joining acrylic is acrylic solvent cement.
Unlike ordinary glue that simply creates a layer between two surfaces, acrylic solvent bonding works by affecting the acrylic surfaces so they join together.
This can create extremely clean seams when done properly.
Place the panels together first.
Secure them so they cannot move.
Then use a fine applicator to carefully introduce the solvent along the joint.
Follow the instructions provided with the specific acrylic bonding product you're using, including ventilation, protective equipment, application method, and curing requirements.
Less is usually better than flooding the joint.
Too much solvent can run across the visible acrylic surface and leave permanent marks.
Step 12: Assemble One Section at a Time
Don't attempt to hold all five sides together while simultaneously applying adhesive everywhere.
Work methodically.
For a basic case, you might:
- Join the front to one side.
- Add the second side.
- Add the back.
- Verify that the structure is square.
- Add the top.
Allow each stage enough time to become stable before introducing unnecessary stress.
Your exact sequence can vary depending on the design.
The important thing is maintaining alignment.
Step 13: Let the Case Cure
Don't mistake "the panels aren't moving anymore" for "the case is finished."
Acrylic bonding products need time to develop their final strength.
Follow the cure time specified by the product manufacturer.
During that period:
- Keep the case on a flat surface.
- Avoid flexing the panels.
- Don't lift the case by one wall.
- Don't place heavy objects on it.
- Don't immediately load it with your collectible.
Patience here can be the difference between a clean case and a joint that fails later.
Step 14: Remove the Protective Film
Once the case is fully assembled and you're finished working around the surfaces, carefully remove the remaining protective film.
This is usually the most satisfying part.
What previously looked like several cloudy plastic panels suddenly becomes a clear acrylic display case.
Check the surfaces for adhesive residue, fingerprints, or dust.
Step 15: Clean the Acrylic Properly
Don't immediately grab household glass cleaner.
Acrylic should be cleaned differently from ordinary glass.
For routine cleaning, use a clean, soft microfiber cloth with lukewarm water and a small amount of mild soap.
Avoid harsh chemicals and abrasive materials.

Proper care becomes particularly important with DIY cases because you've already put several hours of work into building one.
Common Mistakes When Building an Acrylic Display Case
1. Forgetting Acrylic Thickness in the Measurements
This is probably one of the easiest mistakes to make.
If panels overlap one another, acrylic thickness affects the final dimensions.
Sketch your joints before calculating panel sizes.
2. Building the Case Exactly to the Object Dimensions
Always allow some working clearance.
Otherwise the collectible may rub against the acrylic or may not fit at all.
3. Removing All the Protective Film Too Early
Leave the surfaces covered as long as practical.
Fabrication involves moving, clamping, positioning, and flipping panels.
Every one of those steps creates an opportunity for scratches.
4. Skipping the Dry Fit
Never discover a dimensional error after applying solvent.
Assemble first.
Bond second.
5. Using Too Much Adhesive
More adhesive does not automatically create a better joint.
Excess solvent or glue can run onto visible surfaces and create marks that are difficult or impossible to remove.
6. Using the Wrong Cleaner
Acrylic isn't glass.
Use products and cleaning methods that are compatible with acrylic.
7. Rushing
Acrylic fabrication rewards patience.
Careful measuring, clean cuts, square joints, and controlled assembly will make a much bigger difference than trying to finish the project quickly.
How Much Does It Cost to Build an Acrylic Display Case?
The DIY cost depends heavily on:
- Case size
- Acrylic thickness
- Sheet size
- Material supplier
- Cutting equipment
- Adhesive
- Tools
- Finishing supplies
- How much material is wasted during cutting
If you already own the equipment, DIY fabrication can be a fun and economical project.
If you're purchasing an entire acrylic sheet, specialty tools, solvent cement, clamps, and cutting equipment to make one case, the economics can change quickly.
That's where comparing DIY against a made-to-size case becomes worthwhile.
Should You Build or Buy a Custom Acrylic Display Case?
Building one yourself can be a fantastic project.
Choose DIY if:
- You enjoy fabrication.
- You already have the necessary tools.
- You want to experiment with the design.
- You're comfortable cutting acrylic.
- The building process is part of the fun.
Having one made may make more sense if:
- You primarily care about the finished display.
- You don't own acrylic fabrication tools.
- Your measurements are unusual.
- You need several identical cases.
- You want precision-cut panels.
- You don't want to buy an entire sheet of acrylic for one project.
And that's exactly why Aegis Acrylic offers custom-sized cases.

That means you can design the project yourself while letting us handle the precision cutting.
Frequently Asked Questions About Building Acrylic Display Cases
What thickness acrylic should I use for a display case?
For many smaller and medium-sized cases, 3mm acrylic is a practical option. Larger displays or cases where additional rigidity and a heavier appearance are desired may benefit from thicker material such as 6mm acrylic.
Can I build an acrylic display case without a laser cutter?
Yes. Simple acrylic boxes can be produced using traditional acrylic-cutting methods. A laser cutter becomes particularly useful when you need highly precise dimensions, repeatable parts, holes, slots, curves, or more complex shapes.
What glue should I use for an acrylic display case?
Acrylic solvent cement is commonly used for permanent acrylic fabrication. Always select a product specifically designed for the type of acrylic you're using and follow its manufacturer's application and safety instructions.
Should an acrylic display case have a bottom?
It depends on the design. Many collectible displays use a five-sided acrylic cover that sits over a separate base. Others use a fully enclosed box or removable panel.
How much larger should a display case be than the collectible?
There should be enough internal clearance to place and remove the item without rubbing against the acrylic. The exact amount depends on the object and desired presentation.
Can I make a custom-size acrylic display case?
Absolutely. That's one of acrylic's biggest advantages. Once you know the required interior dimensions and panel layout, the enclosure can be built around virtually any suitable rectangular display item.
