Yamaha R3 Quadlock Adapter

thingiverse

I made an adapter to make the Yamaha R3 stem mount usable. The triple clamp screw was bought off of aliexpress. I needed a screw that had a hole in the middle that I could bolt something to and there was only one I found, I used an M10x20mm bolt. The adapter is meant to replace the stem mount part that expands in a hole. It has a similar star pattern that bites into the other side, so it won't move from bumps.
