Since keylights from big name companies cost so much money, i decided to make use of the LED backlight board for the color lithophane frame as a keylight.
The design is rather simple, so it is easy to assemble and dissamble the diffuser as well as the LED lightboard. I printed the frame laying down and the support was such a pain to remove so you can try print it standing up.
The keylight frame has a male GoPro mount, so you might need to buy a GoPro female mount if you want to mount it on a tripod or a desk mount.
Here's a video I made so you can see how to assemble it and how it performs:
