This is a very simple dice tray. You can use it for any game or dice; I use it for D&D, but you can do whatever you like. I made it small (13cm by 13cm wide, 18cm tall on the outside) so that it can be printed on a larger variety of printers. (And so that I can fit it in my backpack.) Scaling should work fine, though. All of the inside edges are curved at the bottom, but if you want a non-curved version to put felt in, I would happily make a version like that.
*I don't have any real pictures yet because I wanted to take them when I got a new set of dice, which will be Sunday. Until then, you can just look at the STL pictures. You can ignore those corner things in the Tinkercad shot; they are so small in reality that a 3D printer wouldn't even see them.
Designed with Tinkercad, printed on a Prusa Mini+.
