The box can be used for 5 lithophane pictures. I have already gifted the box twice myself.

The pictures should be 140mm x 140mm and have a frame of 3 to 4 mm.

For easier assembly, it is recommended to use 139mm x 139mm with a 3mm border.

For the lighting, I used simple LEDs from Aliexpress. See link. The current diameter is 80mm, but this can be easily adjusted with the included CAD file. Similarly, a different light source can certainly be easily integrated. I glued in the lamp and cable, but this is not necessary.
