A&M lightbox
Original example printed with Bambu basic PLA black, white, Kingroon gray PLA, and Filacube maroon PLA2.
I was pleasantly suprised to see the maroon would let light through after doing my transparency test swatch. More than .6 height and its over for it though.
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!
