12mm Diameter 3-Crayon Mold

A simple crayon mold designed as a quick craft project for my children to use up lots of broken crayons.

Print in your choice of high[er] temp materials - I printed in ABS - seems to work ok for wax. 0.16mm layer height - layer lines aren't too bad in my opinion. Bolt holes are made for 6mm bolts - and they are intended to be snug to make sure that two halves of the mold align properly. Bolt length in images is 35mm; you can get away with 30mm. I used wing nuts to make it easy to open.
