Brass and Silver Rings
Starting with a 1” x 1” square block of brass, I milled a slot down the center and created a line of rings.
I then modeled my favorites in SolidWorks, 3D printed them in several ring sizes, and had a foundry cast them in the NYC Jewelry District.
Upon receiving the raw castings, I sanded and polished them to a bright finish.

Phones in 2014 had much worse cameras than I remember.
