Designed and printed this box for my wife for Mother's Day to hold six 80mm x 80mm x 2mm lithophanes (just slide in from the top), and to be lit up using a short section of LED lighting strip. I used Fusion360 for design, Simplify3D for slicing, and FolgerTech FT-5 and Kossel2020 printers for 3dprinting. Assembled with some aluminum foil, 3x M5 screws, and a 12Vdc power supply.

I printed at 0.4mm (with a volcano nozzle), but any resolution will work. Supports are necessary, and sort of a pain to take out.
