I'm low on storage space and there was a lot of air in the Marvel United boxes. That and the clear plastic covers are a bit finicky.

I slightly massaged the https://www.thingiverse.com/thing:4853377 because I didn't have the magnets they had on hand, also their lid, while cool was a bit too tall. (Holes are 5.2mm diameter and 4.75mm deep)

You will need to print
4x MU_Mag_Token_Tray.STL

MU_Villain-Tray (support recommended)
and either:

OR all of the following:
