I've been playing lately with modeling and 3D printing jewelry. I am not usually wearing rings, but it seems I enjoy designing them... :D
Ring 1
Ring 2
Ring 3
(I don't know why adding attachments doesn't work)
Attachment 9401
Programs: Rhino & Grashopper
Printer used: Form1+ and Form 2
I also decided to add two of the rings for Myminifactory contest so they can be downloaded from here:
