Magnetic dice case

I am still learning the basics of 3d design using Onshape so i decided to make this dice vault style case to fit a set of 7 polyhedral dice to both help me learn and to house some of my many sets of dice. the lid is held in place by 4 4x2mm round magnets.

EDIT: added an alternate design with chamfered inside instead of filleted. also fixed the magnet holes to be a more flush fit.
