While searching for something completely different I found set of metal dice, more than twenty years old, from the years I got to play GURPS and Dračí doupě (Czech knockoff of DnD).

So I had to design a nice case for them. There is a lot of designs available, but I was unable to find the right one for my size of dice and magnets I had available (8x4 mm). So I designed one myself.

I used the Prusament Mystic Green and Mystic Brown filament and it looks very nice.
