The perfect portable dice box and rolling tray. Can easily hold 20 dice, 3 or more miniatures, and a couple of pens/pencils (even more dice)! Cut and glue felt, foam, or cork to the sides for protection and a much quieter experience.
There are slots for 6x4x2mm magnets built into the lid and base to keep it secure.
I printed mine in PETG, but PLA should work just fine as well.
Note: I can't find 6x4x2 magnets anymore, so I added another variant to fit 10x4x2mm magnets. I don't actually have any of those magnets and haven't printed this version to test whether they fit perfectly or not. https://www.amazon.com/MIN-CI-Rectangular-Refrigerator-Industrial/dp/B09M6BJK5N/
