It fits in the frame perfectly. The inside is a bit too thick so a cable wouldn’t fit in but I filed it a bit out and it seems to be holding. I reckon if I make it in alloy then it can afford to be a bit thinner and it should be perfect
Great, I wouldn't trust this one too much but if it's holding up it's holding up. Worst case would be riding home on a the small ring, right? I've attached the file for the final print, to put it in the public domain.
No way! It fits?
