Are you a passionate LEGO collector with shelves full of stunning creations that deserve to be showcased? Building your own LEGO display case is not only a fun DIY project but also a cost-effective way to protect and display your beloved sets. In this comprehensive guide, we’ll walk you through the entire process, from gathering materials to adding the final touches. Let’s get started!
1. Plan Your Display Case
Determine the Size
Before you begin, measure the LEGO sets you want to display. Consider the height, width, and depth of your largest models. This will help you decide the dimensions of your display case. For example, if you have a large Star Wars Millennium Falcon set, you’ll need a case with enough vertical and horizontal space to accommodate it comfortably.

Decide on the Style
There are several styles of LEGO display cases to choose from. You can opt for a simple, wall-mounted shelf, a multi-tiered cabinet, or a sleek, modern display box. Think about the overall aesthetic of your room and the look you want to achieve. If your room has a minimalist design, a clear acrylic display case might be the perfect fit.
Sketch a Design
Once you’ve determined the size and style, it’s time to sketch a design. Use graph paper or a digital design tool to create a detailed plan. Include measurements, the location of shelves, and any additional features like lighting or doors. This will serve as your blueprint throughout the building process.
2. Gather Your Materials
Wood or Acrylic?
The two most common materials for LEGO display cases are wood and acrylic. Wood offers a classic, sturdy look and is easy to customize. Plywood, MDF (Medium-Density Fiberboard), or pine are popular choices. Acrylic, on the other hand, is lightweight, transparent, and provides a modern, sleek appearance. It also allows for unobstructed views of your LEGO sets. You can purchase pre-cut acrylic sheets from a hardware store or online.

Tools
You’ll need a variety of tools depending on the materials you choose. For a wood display case, you’ll need a saw (such as a table saw or hand saw), a drill, screws, a measuring tape, a level, and sandpaper. If you’re using acrylic, you’ll need a ruler, a utility knife, a heat gun (for bending acrylic), and acrylic adhesive.
Additional Supplies
Don’t forget to gather other essential supplies like hinges (if you’re adding doors), handles, LED strip lights (for illuminating your display), and non-slip pads to keep your LEGO sets in place.
3. Cut Your Materials
Measuring Twice, Cutting Once
Whether you’re working with wood or acrylic, accurate measurements are crucial. Double-check your measurements before making any cuts. If you’re using wood, mark the measurements on the boards with a pencil and a straight edge. Use a saw to carefully cut the pieces to size. When cutting acrylic, score the surface with a utility knife and a straightedge, then gently bend the sheet along the scored line. You can use a heat gun to soften the acrylic for more complex bends.

Sanding and Finishing
After cutting the wood pieces, sand the edges to smooth them out. This will prevent splinters and give your display case a professional finish. If you’re using acrylic, make sure the edges are clean and free of any rough spots. You can use fine-grit sandpaper or a polishing compound to polish the acrylic for a crystal-clear look.
4. Assemble the Frame
For Wood Display Cases
Start by assembling the frame of your display case. Use screws and a drill to join the pieces together at the corners. Make sure the corners are square by using a carpenter’s square or a right-angle clamp. Reinforce the joints with corner brackets for added stability. If you’re adding shelves, measure and mark the positions on the side panels, then attach the shelves using screws or wood glue.
For Acrylic Display Cases
Apply acrylic adhesive to the edges of the acrylic sheets and carefully join them together. Use clamps to hold the pieces in place until the adhesive dries. You can also use clear acrylic corner connectors for a more secure and professional-looking finish. When adding shelves, use acrylic supports or brackets to hold them in place.
5. Add Doors or Covers (Optional)
Installing Hinges
If you want to protect your LEGO sets from dust and damage, consider adding doors or covers to your display case. For wood doors, attach hinges to the door and the frame using screws. Make sure the doors open and close smoothly. For acrylic covers, you can use magnetic strips or small clips to secure them in place.
Handles and Locks
Add handles to the doors for easy opening and closing. You can also install locks if you want to keep your display case secure. There are various types of locks available, such as key locks or combination locks.
6. Install Lighting (Optional)
LED Strip Lights
Adding lighting to your LEGO display case can enhance the visual appeal of your sets. LED strip lights are a popular choice as they are energy-efficient, easy to install, and come in various colors. Measure the length of the display case and cut the LED strip lights to fit. Peel off the adhesive backing and stick the lights along the top or bottom edges of the case. Connect the lights to a power source using a power adapter or a battery pack.
Dimmer Switches
For added control over the lighting, consider installing a dimmer switch. This allows you to adjust the brightness of the lights to create the perfect ambiance for your LEGO display.
7. Place Your LEGO Sets
Organizing Your Collection
Before placing your LEGO sets in the display case, take some time to organize your collection. Group sets by theme, size, or color for a visually appealing display. You can also use risers or platforms to add height and depth to your display.
Securing Your Sets
To prevent your LEGO sets from shifting or falling, use non-slip pads or adhesive putty to secure them to the shelves. This is especially important if you plan to move the display case or if you have children or pets in the house.
8. Add the Final Touches
Cleaning and Polishing
Once your LEGO sets are in place, give the display case a final cleaning. Wipe down the surfaces with a microfiber cloth to remove any dust or fingerprints. If you’re using acrylic, you can use a specialized acrylic cleaner for a streak-free shine.
Personalizing Your Display
Add a personal touch to your display case by adding labels, nameplates, or custom artwork. You can also display LEGO minifigures separately on small stands or in glass domes to add variety to your display.
Tips and Tricks
- Test the Fit: Before fully assembling the display case, dry-fit the pieces together to make sure everything fits properly. This will save you time and frustration in the long run.
- Safety First: When using power tools, always wear safety goggles and follow the manufacturer’s instructions. If you’re using a heat gun to bend acrylic, work in a well-ventilated area and keep the heat gun at a safe distance from the material.
- Get Creative: Don’t be afraid to think outside the box and add your own unique touches to the display case. You can paint the wood, add decals, or use different types of lighting to make your display truly one-of-a-kind.
Building your own LEGO display case is a rewarding project that allows you to showcase your creativity and passion for LEGO. With a little planning, some basic tools, and a lot of enthusiasm, you can create a beautiful and functional display that will be the envy of all your fellow LEGO collectors.
