The MK8 extruder drive gear is a critical component of a 3D printer extruder, responsible for reliable and precise filament feeding into the hotend. Made from high-quality stainless steel, it offers excellent durability, wear resistance, and consistent performance even during long printing sessions.

Thanks to its 7.2 mm circular toothed profile, the gear ensures smooth and even force transmission to the filament without slipping or deformation. It is designed for 1.75 mm filament and is compatible with most MK8-type extruders, including both direct drive and Bowden configurations.

The gear is secured to the motor shaft using an M3 set screw, providing a firm and stable attachment with no unwanted movement during operation. Precise dimensions make installation quick and straightforward.
