I've seen lots of dice cases for Poly sets, but none for games that use only d10. This was designed specifically to hold a Chessex 10d10 set. There's a little extra clearance so slightly larger d10s should fit, but this means there's enough space for the dice to rattle out of their wells. I cut a triangle of felt to line the inside of my box lid, but thin foam could also work well.
You will need 6 magnets, 6mm x 3mm cylinders, to close the box.
The lid is also designed with a slight rounded corner against the top. You can print it top down against the bed but watch the bridging perimeters. Alternately, I printed mine with the open side down, turned on brim and supports, and turned up the support XY spacing to 10mm. This left ample room to insert a screwdriver between the outside wall and the support to pop them free, and prevented supports from being generated inside the magnet holes. The base I printed open side up without supports.
Designed with a blank lid so you can add a design of your own!
