Some dwarf themed coins I made for games like Caverna.

The stl files are all single faced, coins typically don't print well at all on the face down side, and the flat sides glue together super easily, I can't even see the seams on most mixed in with the print lines. I printed mine out of abs and acetone welded them together.

The dwarf face is original art (my wife) the other three are modified SVGs from
