- A wicked little filament drive gear made from stainless steel with really sharp little teeth cut into it.
- These are carefully manufactured on a synchronised CNC processs which gives a sharp, consistent, and clean cut tooth profile that has incredibly good grip.
- We've tested these with 1.75mm filaments, from the soft and delicate flexibles to hard and abrasive materials like Carbon-Fibre PLA. All with great results.
- These are a great match for our 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.
