I printed this "easy to print" version with my China CTC.
It worked out pretty good.
I freed the balls with a small pliers and then lubed it up with dry PTFE lube.
The lube didn't only make things spin longer but also stopped the balls from getting stuck.
The Bearing is spinning pretty nicely now.
If you don't have dry PTFE (get it!) use oil with very low viscosity.
Most oils and greases are made for higher speed/temp/stress and will make your bearing
inefficient at lower speeds.
Thanks for this nice working and fantastic nice looking bearing.
Gonna print the "hard" version soon.
Use dry lube! (E.G PTFE Spray)
