This is a tooth box I designed for my son whether it's for your own child or as a thoughtful gift for a friend or family member, my Fairy Tooth Box is sure to bring joy and wonder to any child's tooth fairy experience.

Printing:
I used the following settings to print all of the parts:

20% gyroid infill
0.2mm layer height
3 walls
No supports
Print all models in the default orientation of their respective STLs. 
The tolerances should already provide a good fit for the lid.
