Custom Cabochon Template and Dop Stick

This is intended to be a cabochon cutting template that either replaces the dop stick or mates with it.

##Features
* Dimensions can be customized to create any sufficiently large round or oval cabochon shape. The length and diameter of the dop stick (or socket) can be adjusted.
* Texture can be enabled on the surface of the template to provide better adhesion from glue or wax.
* A socket (hole) to receive a dowel will be generated if the dop stick is disabled - unless the size of this hole
