NASA Lightbox - 3D Printed Wall Decor // NASA LED Wall Sign

Bring a piece of space history to your walls! This 3D-printable version of the iconic NASA "Meatball" logo is designed as a functional LED Lightbox. The model is modular and optimized for multicolor printing. I have already pre-colored the .3mf file in the Elegoo Slicer (Cura-based) to save you the hassle of painting faces manually. Key Features • 3MF Included: Pre-colored file with distinct layers for White, Blue, and Red. • LED Ready: Features a discreet cable cutout at the bottom for USB cables or LED controllers. • Easy Wall Mounting: Integrated "keyhole" hanger on the back for a secure fit on a nail or screw. • No Supports Needed: The internal geometry is designed to print cleanly without support structures. Important Note on .3mf Compatibility This file was prepared in Elegoo Slicer. If you import this into other slicers (like PrusaSlicer or Bambu Studio) and the colors do not appear immediately, the parts are still separate objects. You can simply re-assign your filament colors (White, Blue, Red) to the individual parts with a few clicks. Recommended Print Settings • Material: PLA • Layer Height: 0.2mm • Infill: 15% (Gyroid or Grid recommended). • Supports: None required. Legal Notice This model features the official NASA logo. Please note that NASA's logo usage is subject to strict guidelines. This model is intended for private, non-commercial use only. LED Assembly • LED Placement: Stick your LED strips (5V USB or RGB) directly onto the flat back panel inside the housing. A spiral pattern ensures the most even light distribution. • Cable Management: Feed the power cable through the integrated cutout at the bottom of the case. • Assembly: Apply a thin layer of glue to the rim of the housing and bond the printed NASA logo onto it. • Mounting: Use the integrated keyhole hanger on the back to securely mount the lamp to your wall.
