thingiverse

Circular mold housing with triangular registration keys built in. Outer diameter is 5", inner diameter is 4.75", and height is 2.75". Each registration key is 0.275" long & 0.3" tall. Designed for making dice molds, but of course you can use it for whatever you can think of. This can fit about 11-12 standard sized dice max - of course, it depends on how close together you position them. No supports needed.
