Ball joint - Cheap and more reliable alternative to Magnetic joints

Very nice alternative to magnetic joints.

- Cheap, just print and glue (compatible with any effector or carriage that uses a 12mm round magnetic)
- Much stronger than a magnet joint
- If you have a ball stud rods (10mm) you can use them, just press fit
- If you wish you can print the male ball joint to glue in your 6mm rods, but you need to acetone vapor the thing to have a smooth movement, I tested only with steel ball studs.
- Easy and fast to change tools
- No backlash
