Tiny ring size. Should find a way to make it easily changable to ring sizes people know. I think i'm size 8 and its small

Unless I'm not assembling it right the tolerances on at least one of the pieces is a little bit tight. The long piece should be a little bit higher, I think.

Also, what size righ is this? All the holes seem to be slightly different sizes.

I'm not sure what you mean by long piece. Are you referring to the snap together hinges? I did notice that the tolerance is tight between two of the rings, and I will try and make some tweaks to the design.

I believe the they are 9.5, 10, and 9, but I really just adjusted everything to fit my left index, middle, and ring finger circumferences.

So it might be good to unitize the whole thing, make a version where all the sizes are 1mm across, then everyone can scale it up to their largest finger and just wear it there. I may do that myself.
