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

Used on my Ender 3 v2 with great success once esteps were calibrated

These are exactly what I needed and they work great

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.

Im only getting about 12 hours of print time before the teeth are too warn to work. I have only used PLA. The stock brass drive gear lasted MUCH longer

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

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

They work great the higher teeth count eliminates grinding.

perfect last Way longer than the brass ones buy one pack and they will last a long time

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.

Working well so far. Ran a kilo of carbon fiber through so far without issue. Do wish they had two grub screws instead of just one.
