Hi! I received the first print of my ring in polished bronze. The thickness is at the limit the of the material, the upper part is 0.7 mm thick all over the surface! I'm very happy because It is light but it also seems very solid. You can find more here: https://www.shapeways.com/designer/StefanoAlberti I'm thinking of doing a stainless steel version slightly thicker. Please give me a feedback, good or bad, it will help me improve! Thanks!
