It isn't ready for the general population yet. If someone wants access to test it and give feedback so I can develop it faster, I would be up for that. I have a bunch of stuff to add but this should be getting pretty close to functional. I printed some out last night to try on a 3/8" rod with 625zz bearings.

I am more curious about tiny slips at fast speeds. I have serious doubts about accuracy for X or Y axis movement due to tiny slips from speed. But who knows until you try it.

It's over on Thingiverse!

I posted it here, because I didn't design it & shouldn't put it in STL sharing. Who'll be first to give it a go?
