Before You Start

A few quick checks will make assembly easier and help protect your acrylic panels.

Check All Parts

Lay out the base, side panels, top panel, screws, connectors, LEGO studs and support stand if included.

2
Remove the Film

All acrylic panels have protective film applied on both sides. Remove it before assembly.

Connector Guide

A quick reference for the fittings used during assembly.

●
Connectors 

Used to join acrylic panels together. Insert them into the pre-drilled holes before attaching the next panel.

↔
Special Connector

Used where two-piece base, top panels or shelf meet. Only included with display cases that require it.

+
Screws

Tighten gently until secure. Avoid overtightening, as excessive pressure may damage the acrylic.

Assembly Help

Common questions that may come up while assembling your display case.

The screw holes do not line up. What should I do?
Confirm the orientation of all panels, realign the panels and connectors, then tighten the screws gradually once everything is sitting correctly.
The top panel does not fit correctly.
Check that all four side panels are straight, fully connected and sitting in the correct position. Slightly loosen the side screws if you need more movement for alignment.
My case does not include studs or a support stand.
This is normal. LEGO studs, support stands and other accessories are only included with selected display case models. Simply skip any step that does not apply to your case.
How tight should the screws be?
Tighten the screws only until the panel and connector are secure. Do not apply excessive force or overtighten the screws.
My display case looks slightly different from this guide.
Different display case models may vary slightly, and our designs may be updated over time. The general assembly method remains similar.
