This lightbox features the Nuka Cola label, printed in Bambu PLA Basic Red and White. I printed the back in Red as well, but you could do it in Black if you prefer. The lightbox has a small hole on the back to pass wires through to power the LED lightstrip. The model has the inside back wall of the lightbox shell painted white, to help reflect light towards the front of the box. If you prefer, you could print the back shell as a single color and line the interior with aluminum tape or other reflective material.

I originally designed this at almost full bed size, but scaled it down to 150mm. The 3mf file here is the smaller size, exactly as I printed it. The STEP file attached is the original, larger size.

This is my first lightbox design, so if you have any suggestions please feel free to share.
