V Groove Roller
thingiverse
This is a 90 degree V-groove roller for linear motion. I had some extra 696 bearings so this is sized for those (6mm shaft diameter). This was a test for a machine I'm building and it ended up working really well, so I thought I'd upload it. Instructions I put some little rings around the bolt holes to hole them up on the bridge, but that didn't turn out spectacular. It might print better upside down, but then the flange for the bearing would have problems. Print 2 and assemble with 3 M3x10 bolts, nuts, and a 696 bearing.
