Blank Ring Based On A Sphere

thingiverse

This is a blank ring made from a sphere by cutting out a cylinder first. The cylynder was not centred and then I cut of the top and base ... Then I printed a white PLA-ring - just to try it out, to check if it´s comfortable. The Idea was to create it in a way, so that it has wide areas of a shiny surface after being casted and polished. I think it worked, as you can see in the simulation as well as on the silver-casted ring (with a masonic theme).
