I have created a Vertebrae inspired ring using Z-Brush. We suggest using a DLP 3D Printer to print this item as its a smaller item but your welcome to try any machine you have.
This would require supports and is able to be cast into a metal.
I have included the following file formats:OBJSTLFBX
We can design any pattern ring, if you do require something specific please dont hesitate to drop us a message.
Many thanks for the support!
