A James Bond Sighted Lightbox, like the opening credits in most of the movies of past.
I used Protopasta Blood of My Enemies for the red, Sliceworx Omni White and Polymaker Black PLA.

Any LED strip will work. I used an App controllable strip over a remote one.

I put the LED's on the bottom of the base not the sides, the base is deep enough to add a diffuser, included, and it has standoffs built in to spot glue the diffuser on, i used hot glue gun, just a dab.
Glue the Hanger 4 back on after you print it.
