Fallout Shelter Sign – Multi-Color / Glow-Friendly

This is a Fallout-style shelter sign designed from scratch in CAD and intended as a clean, wall-mounted decorative piece. I originally made this for a friend and am sharing it for anyone who wants a classic retro-apocalypse sign for their space.

The model size is 300 mm × 200 mm, which balances visibility and printability while keeping text and symbols crisp.

📂 Included Files

Three files are included so you can choose the workflow that best matches your printer and filament setup:

• Fallout Shelter.step
  Full CAD source file for easy customization (size, thickness, text, symbol depth).

• Fallout Shelter.3mf
  Standard print version using normal infill for all parts.

• Fallout Shelter_solid.3mf
  Alternate version where the text and triangle symbols are solid mesh instead of infill.
  This version was created specifically for glow-in-the-dark filament, but is useful anytime you want fully solid details.

🎨 Multi-Color / Multi-Material Friendly

Each major element (background plate, text, and triangle symbols) is a separate object, making it easy to:

• Assign different colors per object in your slicer

• Use different materials (example: standard PLA base + glow filament text)

• Print on single-extruder printers using color swaps or on multi-material systems

The photos show just one example — feel free to get creative.

🖨 Printing Notes

• Designed to print flat on the build plate

• No supports required

• Works well with standard infill for the base

• The solid version is recommended for glow filament for better brightness and consistency

This model was printed on a Creality K2 Plus using Atomic Filament and Inland Filament, but it should work well on any comparable FDM printer.

Scaling is supported, but text and symbol clarity are best at the original size.

🧰 Customization

If you want to:

• Resize the sign

• Change the wording

• Adjust thickness

• Modify symbol depth

…the STEP file is included to make those changes straightforward.
