12x12 LED Shadow Box Display – Slide-In Front Panel – 60mm Pendant Compatible
This is a purpose-built 12” x 12” shadow box designed for clean, professional display builds. It was created specifically to accept a 12 x 12 inch glass or plexiglass front panel that slides smoothly into a recessed top channel for a clean, frameless look.

I’ve been printing and using these as going-away gifts for military friends, and the design balances durability, clean presentation, and ease of assembly.

📐 Overall Dimensions
Internal display area: 12” x 12”
Front panel size: 12” x 12” (glass or acrylic/plexi)
Front panel thickness supported: standard 1/8" acrylic or glass works perfectly
Light opening: Designed to accept a 60mm pendant LED light
Recessed slide-in channel built directly into the front frame
Integrated top mount area for LED with diffuser support
The plexiglass or glass slides vertically into the front recess and sits securely in the lower channel. No adhesives required.

💡 Lighting Compatibility
Designed for 60mm round pendant LED lights
Works with common low-profile puck/pendant style LEDs
Top cavity supports a diffuser insert for clean, even light spread
Creates a focused top-down spotlight effect inside the box

🛠 Print Details
Printed on a Creality K2 Plus
Sliced using normal snug supports
Supports are minimal and clean up easily
Designed for strength and clean layer alignment
Walls are thick enough to prevent flexing once assembled
Because of the size, make sure your printer supports 300mm class builds (or larger).
