It can contains around 100 card with sleeve. I tested it with Dragon Shield sleeves.
The lower box has enough space to contains several dice/tokens.
Each part of the box has also magnets hosuing (2 x 10 mm) for keeping all closed.
I suggest epoxy double component gluing the magnets, just take care of the magnetic verse.
I tested with full cards and shaking without accidental opening.
The cover can be back flipped after opening to keep the inner part exposed.
I used PETG for printing a good balance in resistance but avoiding the wrapping effect of the ABS/ASA
