2 part silicone mold boxes for dice making
thingiverse
Small is sized for standard dice (20mm D20), medium fits up to 27mm D20. I printed in PLA, worked great. Ideal for making cap molds though they should work for sprue molds too. To use, place the die on a piece of painter's tape (I love frog tape) and then place the mold box over and seal the bottom completely with tape. If registration markers are desired, place that side down. For second pour, leave registration markers up. Clamps can be used though the pieces click together with a nice friction fit so they aren't required.
