VERY happy with this new mold! I only have to sand/polish one face (the 20) this way, rather than 4 faces (the 20 and the 3 that touch it) plus the resin reservoir in the cap means I won't get air bubbles
I tested it out with another geode design, like the first die I made— this time a white stone with a glittery black interior 🔳🔲🔳🔲🔳
