DIY LEGO Display Case: Measure the Model and Plan Access

A DIY LEGO display case needs to fit the finished build in the pose you want to display. The important measurements include the model, its support and the space required to place and remove it. A snug empty box can still be the wrong display if a wing, roof or minifigure catches on the opening.

This is a design guide with a documented model example. It does not claim that CubeBuff has fabricated or tested the illustrated enclosure. For sheet joining, use the separate acrylic panel and assembly guide.

1. Record the exact set and display pose

Write the set number on your drawing. Photograph or sketch the final orientation, including open doors, a raised bonnet, wings, antennas and any figures placed beside the model. Those choices define the envelope you need; a product name alone does not.

For example, LEGO lists Porsche 911 10295 at over 10 cm high, 35 cm long and 16 cm wide. These are published model dimensions, not an enclosure cut list. Measure your own completed Turbo or Targa configuration, particularly if you display moving parts open.

2. Measure the model and support as one assembly

Use the widest, deepest and highest points in the chosen pose. Add any display stand, nameplate or diorama base you intend to retain. A model on an angled support may need more height and a different footprint than the same model resting on its wheels.

Mark where the load reaches the base. A clear top or side panel should not become an accidental support for a roof, wing or leaning stand. Keep the model’s support independent of the removable cover.

3. Keep four allowances separate

• Display clearance: the visible space around projecting details.
• Access clearance: room for hands and for the model’s route through the opening.
• Manufacturing tolerance: the variation the fabricator allows in cuts and joints.
• Material movement: the allowance required by the actual panel and fastening system.

Do not combine these into an unexplained “add a few centimetres” rule. Record each decision on the drawing. A geometric width can be expressed as the measured model width plus left and right display clearances, but that still leaves the opening and joint design to resolve.

4. Choose how the model enters

A lift-off cover lets you position the model on an exposed base first. It needs room above and around the case when removed. A front-opening design can suit a fixed shelf, but the clear opening must admit the complete model and your hands without using delicate LEGO elements as handles.

Make a full-size cardboard footprint and a simple opening template. Check them in the intended shelf location. This checks your space planning; it does not prove the strength of the final acrylic construction.

5. Plan maintenance and moving before fabrication

Leave a route to switch off any model lighting and remove accessories without dismantling the case. Decide where the empty cover will rest during cleaning. For a large build, plan how the model and cover will be moved separately, following the set’s instructions for supported sections.

Before approving the order, your drawing should identify the set number, pose, support, required internal envelope, opening direction, material, joint type and base. Ask the fabricator to confirm the structural choices. The manufacturer’s calculation tools distinguish load and support conditions; there is no single LEGO-case thickness.

Can this approach be used for LEGO Star Wars?

Yes, the measurement method also applies to a Star Wars build, but the geometry must come from that exact set and stand. Include the entire wingspan and any tilted presentation. Do not reuse the Porsche example as a drawing for a starship.

Prefer a finished set-matched enclosure? Browse LEGO display cases and confirm the exact number before ordering. The Porsche example belongs in the Icons selection; for Sauron’s Helmet 11373, compare the current Lord of the Rings cases. For characters on individual bases, use the separate DIY minifigure case guide.
