I created an inlay for a parametric box from Printables (https://www.printables.com/model/744407-rugged-box-parametric-no-hardware/files) and the Mario cubes (https://makerworld.com/en/models/247618?from=search#profileId-263891 & https://makerworld.com/en/models/236941?from=search#profileId-252993).
A total of 10 dice from the above models fit into the box.
I also added a picture of Mario to the lid.
The box is printed from PLA and the sealing ring is made from TPU 85
