This is a remix of my lithophane lantern that is compatible with the Bambu Lab 001 LED lamp.
Lithophanes should be 115mm x 145mm x 4mm think. Once printed the legs screw into the bottom of the base and the threaded decorative screws hold the top onto the base. The supports on the threaded screws is pretty stubborn so you may want to adjust those to be easier to remove. I kept them aggressive to minimize the chance of the screws popping off the build plate.
