Original Prusa Extruder Driven Gear (Filament Spur)

Description

This Extruder Driven Gear (Filament Spur) is a direct replacement part for the Original Prusa MINI and MINI+ 3D printers. It functions as the crucial driven/idler gear responsible for consistently pushing the filament within the extruder assembly. Maintaining this component in optimal condition is essential for sustained print quality and reliable operation, as any wear or damage can lead to inconsistent extrusion and print failures.

The Original Prusa extruder-driven gear is engineered with precision and durability in mind. Its primary role is to grip and feed the filament into the hotend for precise extrusion. By ensuring consistent filament feeding, this component actively prevents issues such as slipping or grinding of the filament, which commonly degrade print quality. Replacing a worn gear with this genuine part will restore your printer’s ability to produce reliable and high-quality 3D prints, maintaining the exceptional performance expected from Original Prusa machinery.
