Falcons lightbox we did. Mainly black so unless your using translucent black you won't get any light through.

Original example printed with Bambu basic PLA black, white, red, and Kingroon Gray PLA.

As normal be sure to heat up your hotend to be able to clean any filament that is stuck to the nozzle before sending the print to reduce wisps as much as possible.

The back has a negative cube included so you can move and scale it as you need for installing your lights.

Enjoy and Happy Printing.
