MK8 Extruder Drive Gear 5mm Bore for 3mm Filament 3D Printer
MK8 extruder drive gear with a 5mm bore for 3mm filament, for older printers built around thicker filament.
Price range: See on Amazon
What we liked
- + 5mm bore fits standard NEMA stepper motor shafts
- + Made for 3mm filament systems that newer gears may not suit
- + Simple replacement for worn gears on legacy RepRap machines
Trade-offs
- - Designed around 3mm filament, so thinner-filament users should skip it
- - Confirm tooth count matches your extruder before ordering
