Prusa I3 improved Z axis brackets with spool mount

thingiverse

Human: An enhanced Prusa I3 upper Z-axis bracket for both Basic and Hephestos models. Using precision-engineered ball bearings, this design significantly reduces the oscillations of the Z-axis jackscrew, resulting in improved print accuracy and consistency. A key feature is the incorporation of 45-degree mounting holes, allowing users to attach a spool without adding unnecessary components that may interfere with cable management. Instructions: To assemble the bracket, you will need two high-quality ball bearings measuring 10x5x4mm or 10x5x5mm (outside diameter, inside diameter, and height). Insert the ball bearing into the largest hole available.
