This is a 26 Tooth Extruder Drive Gear that fits into extruder assemblies and firmly grips the 3D Printing Filament to move it towards or away from the hotend assembly. It is capable of high torque without damaging the filament, and fits directly onto the shaft of NEMA 17 Stepper Motors, making it simple to install but effective at assisting with consistent extrusion.

These particular Extruder Drive Gears are made for the TEVO Tarantula’s older style of extruders, and ensure that the filament is moved into the melt zone when extrusion is happening, while pulling it back when the hotend is moving across the print bed. This translates to smooth and consistent extrusion, with improved print quality, and reduces the chances of clogging or similar problems. Although this is a basic little part, it is a vital part in the extruder system, and counteracts the back-pressure of melted filament within the hotend assembly.

Typical Applications for the Extruder Drive Gear - 26 Tooth:

This 26 Tooth Extruder Drive Gear is designed to fit the TEVO Tarantula, but could be used on many other similar 3D Printers, or even in different machines altogether. It is made from brass, which is durable but soft enough to prevent filament damage, and has a tiny form factor to easily fit without requiring any extra modifications.
