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

very easy to install on an ender 3v2 and I didnt even have to adjust my e-steps

Purchased BIQU Extruder Pulley 36Teeth Bore 5mm Stainless Steel Drive Gear for 1.75mm & 3mm 3D Printer Filament (Pack of 5pcs) for 3D printer upgrade. Gears are made of high-quality stainless steel and are a direct fit replacement for Flashforge Adventurer Series 3D printers. Highly recommended!

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

Fit perfectly on my creality cr-10 mini. Still waiting to to see the durability.

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.

Works well

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.

Using this drive gear to grip a brass rod. Nice. Set screws hold tight on extruder shaft. Used a standard allan wrench. Its loose in hex socket, too much force will round the hex.

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.

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