Spherical Joint Models

Two models of spherical joints.

Both are printed with PLA natural (no pigments, better resistance) with a 0.6 nozzle (stronger than 0.4mm) at 0.4mm layer heights, and using a raft to avoid squishing the bottom layer.

* v2b - Has a very little backlash (near to none, got no tool to measure that) and very smooth movements; pull resistance 7+ Kg (first test went to 10Kg, max force depends on how you restrain it, and the wear, so taking the worst value i got ;-) )

* v3 - noticable backlash (maybe 0.5mm), and less smooth operation; pull resistance: couldnt break it, stopped at 14Kg
