Box for Cathedral with MAGNETS!!

I found and printed this Cathedral game, but i was dissapointed by the storage options. So i designed a Board and Box by myself, with Magnets.

There are 4 holes in each corner of both parts, i put 4x10mm magnets in and it holds extremely good. My 6yo son is too weak to open it by himself unfortunatley, i should have started with only 2 magnets.

inspired by those two creations:
