Snare drum 18mm ring model for printing. I made one mesh version of that kind of ring becouse you can find many of them made with seperate rodes that you have to dril and put into the ring.
Youl find fbx version with and without subdivision for making a changes in design. Mesh is made with 10 parts , that are 36 degree so if you planing changing the desing you can simply change one part and array them.
