When I played with my daughter 7 Wonders - Duel, she commented on the cardboard coins. I just got some gold colored filament in and made a quick design, which may work for any boardgame as a substitute. I dialed down the bed heat, so the numbers look alike on both sides. This is still work in progress and I will post single coin stl files over time with various face values. Enjoy!

Added a coin stacker.

Added a single coin stl file for the highest stack. All coins have the same height, so print each file until stacker level is filled. 10 x 5, 2, and 1; 7 x 2 and 1; 4 x 1.
