MK8 Drive Gear for 1.75 mm Filament

These stainless-steel MK8 drive gears are made for 3D printers that use 1.75 mm filament. The 5 mm bore fits a standard motor shaft on many direct extruders. A pack contains five gears for replacement or spares.

Check Shaft and Extruder Compatibility

Verify that your extruder uses a 5 mm motor shaft before ordering. Confirm the gear outer diameter of 9 mm and height of 11 mm match the space inside your extruder body. Ensure the effective diameter of 7 mm suits your filament path.

Stainless Steel Build and Daily Use

The gears are machined from stainless steel for wear resistance during continuous printing. Deep grooves grip the filament securely to reduce slipping. The 5 mm bore presses onto the shaft without a set screw, so alignment matters when installing.
