Brass Filament Drive Gear MK7 Style (Optimized for PLA) 5mm Bore
This brass MK7 drive gear is the industry standard filament drive gear good for all kinds of filament but it excels with 'hard' filaments like PLA. Extra sharp CNC machined 'teeth' grip the filament exceedingly well. An M3 set screw is used to secure the drive gear to a 5mm motor shaft. A direct replacement for many extruders.
