Summary

It's a ring created using a icosahedron as a jewel on top.

Instructions

I've tryied couple of different ways to place the ring on the makerBot's bed. The best result came with this model.

The ring at this model is a size 8. If you would like to adjust it you can add or subtract material from the ring part.

I made white and black versions of it. I like the black the best.

I recommend using an outside raft support to print it clean. It comes out ok without a support too but not as smooth as one might like.

Enjoy :)
