Yes, I would like to try it in stainless steel. The two parts have to be in the same material though (the rendering where there are separate is just to understand the mechanism, but they have to be printed one inside the other). I have to check that the clearance and the wall thickness are OK, before. I will also try to have the nut being printed apart so that it can be screwed into the bolt.

or maybe just the bolt since you want the effect of a Bolt through the finger

cool... i think it would be amazing if the bolt ad its ring were made in stainless steel and the outer ring in any other material... transparent would be sweet
