This is a cover for the litho lamp, showing the logo of Dungeons and Dragons, for short DnD.

The color layer is 1 mm thick. After that layer, you have to change the filament. This should already be configured in the .3mf file.

The box to put the cover and the lights in can be found here: https://makerworld.com/en/models/142296

I recommend printing it with 100% infill, as otherwise you will be able to see the pattern of the infill when the light is turned on.
