Spherical Joint Models

thingiverse

Two models of spherical joints are printed with PLA natural. This material has no pigments and provides better resistance than other materials. The printing process uses a 0.6 nozzle, which is stronger than the 0.4mm nozzle. A layer height of 0.4mm is used to ensure optimal results. Both versions have distinct characteristics that set them apart from each other. Version v2b has very little backlash and provides extremely smooth movements. The pull resistance for this version is around 7+ Kg. In fact, the first test reached a maximum force of 10Kg. However, it's essential to note that the actual force depends on how you restrain it and the wear on the joint. Version v3 has noticeable backlash, which amounts to about 0.5mm. The smooth operation is also less impressive compared to version v2b. Nevertheless, the pull resistance of this version could not be broken, even when stopped at a maximum force of 14Kg. Videos documenting the pull tests are available online for both versions.
