Magnetic Clasp Designed in Zbrush

People have been asking how I model my jewelry.  In the old days it was by hand with polymer clay.  Now I mostly use digital clay, and my favorite software is Zbrush.  Have a look at this magnetic locking clasp that I have been working on for a few months.  I think this is the final design.  It’s going to print right now, and I hope to plan to have it in bronze by the time Maker Faire rolls around ( 3 days!?!?).
