Mandelbulb ring in Sterling silver (92,5% silver)
This model has an inner diameter of 20mm also available with a diameter of 18.5mm http://shpws.me/oS2J - other sizes at request.
I have made many prototypes in different materials before I ordered this one in Silver, many of them are nice (I will post an image of them all later) but this one is perfect, the most detailed and most wearable of them all.
The details are right at the limits for being printable in silver, I got a mail about it from Shapeways... they told me they should TRY to print it... and THEY DID A GREAT JOB! :) - Measured diameter printed in raw silver: 20mm
