1.75mm Hobb-Goblin Drive Gear - 5mm ID
Genuine E3D, premium quality, stainless steel filament drive gear with extra sharp teeth for great filament grip.
These are carefully manufactured on a synchronised CNC process which gives a sharp, consistent, and clean cut tooth profile.
These are a great match for NEMA17 stepper motors with 5mm shafts to create low cost and simple extruders for 1.75mm filament. These gears are similar in effective radius and usage to a Mk8 Drive Gear.
Attaches to a 5mm motor shaft with an included M3 Set Screw.
