Make a custom drink coaster mold with the X-Carve CNC from Inventables

Neo7cnc Coaster Mold 1

I recently did some urethane casting to recreate some small bumpers that were no longer commercially available.  The process was new and interesting so I thought that I’d make some custom drink coaster molds using the X-Carve CNC from inventables.  For the first time, I used a tapered endmill. The taper of the endmill naturally creates a relief angle to the mold, making coaster removal easier once the urethane has cured.  I made several different designs.  The Fusion 360 design file links are below as well as links to other items used in the project.  Thanks to Inventables for sponsoring my creative adventures!
