This model is a remix of Sailor Moon Luna's Box by anfelobo on Thingiverse: https://www.thingiverse.com/thing:4601074
I redesigned the box to be 3x times faster to print and to have multiple colours, the original model takes 11 hours to print vs 3.5 hours for this one.
No supports. No MMU required.
I recommend to use PETG for the box. PLA for the illustration.
You will need to glue the illustration to the box.
The colourful illustration of Luna's uses the PrusaSlicer feature of change colours at height. I made each color of 2 layers of .2. It is enough in with the materials I used, but it might not be enough for everyone, so you can move the negative volume modifiers at will.
The box file uses the sink feature of PrusaSlicer to reduce the bottom shell thickness of the box and lid at will. The shell is 1.8 mm thick.
