I made this Bitcoin-style coin mold for casting silicone and other materials. It has smooth walls and a recessed Bitcoin symbol, so the details come out clean. Just a heads-up: silicone in a silicone mold can be a bit tricky to remove, so go slowly when demolding. Using a release agent helps a lot. You can also try it with wax, resin, soap, etc. Hope you enjoy it — and I’d love to see what you make with it! 😄

Designed this compact 6-star mold for quick silicone pours and wax casting. Each star is 1 cm — great for small decorative pieces. Feel free to remix or scale it for your own use!
