D20 Magnetic Storage Box

This is a simple D20 with a lid and in the main part it has a spot where you can store stuff, like dice, money, candy, and whatever else you can fit. It's 100mm at the largest point (while the top and bottom are connected) I added a tab to easily pull it apart.

I used 5 magnets on the top and bottom that are 7mm x 2mm basic magnets I bought on Amazon in a pack of 200 for $10 or so. I used superglue to glue them in, and they're a tight fit which is exactly what I wanted.

I printed this in place because I couldn't get it to print with supports. I rotated it so one face of one number on each part was in place.

If you have any recommendations on a better way to print this, let me know!
