Gem Ring

Edit 2: New version now with text! http://www.thingiverse.com/thing:11629
(It's a new thing because I needed to use a different license)

A parametric ring with a triangular "gem". Ment to be printed with 2 materials.
After seeing news about makerbot's dual extrusion I decided to design something utilizing it. (even if I can't print it yet T_T )

Edit: Made this kid friendly by adding an optional safety gap so it does not need to be cut off if it gets stuck.
Edit 3: Made the gem's number of sides customizable, and gave it rotation.
