TCU Lightbox
Original example printed with Bambu basic PLA black, white and purple.
It was the only purple I have on hand, use what ever color you feel fits what it should be.
As always be sure to heat up your hotend to clean any old filament that is stuck to the nozzle before sending the print. This will help keep color wisps to a minimum.
The back has a negative cube included in the objects that you can move and scale as you need for your LED installation.
Enjoy and Happy Printing!
