Spherical bearing

thingiverse

A perfect example of a self-contained, single-piece spherical bearing is depicted here. Fabricated without any internal support structures, this bearing was printed with an incredibly fine layer height of just 0.2 millimeters. After completing the print process, the bearing was gently exercised in its middle region to ensure smooth operation, resulting in a freely rotating unit. This impressive feat was achieved using a Witbox printer.
