BIQU Extruder Pulley 36Teeth Bore 5mm Stainless Steel Drive Gear for 1.75mm & 3mm 3D Printer Filament (Pack of 5pcs)

Perfect replacement for sender 3v2. Old brass piece was worn out from clogs but this get it back up and going in no time. Will need to adjust esteps.

I used this as a last ditch attempt to fix the extrusion on my Tronxy P802m. it fixed the extrusion problems and now i get perfect prints every time! i will be ordering again when i need more!

These wheels work and fit perfectly but they wear out quickly. I do a lot printing and have to replace them every few weeks. If you dont print 24-7 this might not be an issue for you. I dont mind having to replace them because of how cheap they are. I like to clean and lubricate my printer regularly so I just replace the wheel when I am doing my preventative maintenance.

Better than OEM.

Perfect fit to replace the worn brass part on my jgaurora A5S.

These have been working great as a replacement for the brass gears so far. I really enjoy the upgrade.

Installed on a Creality CR-10s. Worked like a charm and have a few extra.

replaced the brass gears that keep wearing down..these should come stock with the printers

The original that came with the printer is too cheap and bad. My printer stopped extruding everytime because of them. With these my problem went away. I replace them in an Ender 3 v2

Brass drive gear had worn out and was slipping. Filament would not feed. The steel gear made my extruder work again. I hope steel last longer than brass.
