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

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

Dropped right in, and did not need to recalibrate my e-steps. Good price, and quality.

Good choice. Same size as the original on my extruder so I didnt have to mess with resetting the e-steps. Well built and like the 2 set screws to keep things locked up.

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!

Slightly smaller than standard for my CR-10. Needed to play around with the feed rates to get the right flow. Dramatically less feed slippage though, and Im assuming the steel will be more durable than the stock brass parts.

Not sure what I was using before, but these saved my printer to now print TPU like gang busters! If you are struggling with printing TPU, these are grippy and work. It may not be your only problem, but it will eliminate a variable for why it may not be working..... (TPU is hard to print). Worth the price and should last a lifetime.

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.

Product arrived fast and fit well on my x one 2 and solved my under extrusion issue as well as the constant clicking from the old gear slipping.

Bought these for my 3d printer and they work better than the stock ones! Holds the tubing well and tight! Happy with them.

Works very well, definitely an upgrade from the brass. And fits my JG Maker Magic printer.
