Zero-Backlash Magnetic Ball Joint Rod Ends

These are designed to work with 3/8" balls, 0.230" diameter carbon fiber rods, and N50 cylindrical magnets which are 10mm in diameter and 15m high.
Description
This can be printed with a layer height of 0.2mm or 0.1mm. I use 0.2mm.

Use a shell thickness of 2mm or four layers, so that all of the walls will be printed with concentric circles, instead of back-and-forth infill.

I use a 3/8" ball end mill to gently clean out the ball bearing sockets.

Note: I have to print out two to four of these at a time, to get the correct dimensions.

I use these with my magnetic effector: https://www.youmagine.com/designs/kossel-plus-magnetic-effector

And magnetic carriages: https://www.youmagine.com/designs/kossel-plus-magnetic-carriage--2

Contact [email protected] if you need an inexpensive source for the ball studs or magnets.

Note: This has been my most popular published thing on Thingiverse. Since designing these, I've had rod ends CNC machined out of Delrin, which work even better. I have them for sale for $15/set of 12. Also my CNC machined ball studs are $18/set of 12.
