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

Much better than stock... This was a nice upgrade to my stock Monoprice i3 clone.

Fixed my Maker select V2 with these, dont know if these match the factory gear as I dont think mine had a factory gear in it when it failed. But it matched whatever mine had. Only critique is that the gears seemed like they got banged around in transit so there were some light existing marked/gouges on them. I suspect its not an issue, I just used the one with the least and it worked great.

Good gear, ID is 5.04mm, OD is 10.95mm. Seems to be really good quality and will last a long time extruding pla and petg.

I bought these last year and replaced all my printers with these. And they are far better then one comes stock. The stock wore out so quick. Once I put these on i haven had any problems with filament not getting pulled or filament slipping. there are currently being used for my CR-10s and Hatchbox alpha and not one issue. These are really high quality and at this price point its hard not to get them. I highly recommend getting these and having some lying around in case anything happens. Its better to have spares then to be down while new ones get shipped. Again these are much better then stock. Highly recommend!

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.

I was having clogs and extruder gear clicking sounds...turns out the teeth on my old gear had started to wear down. After checking my retraction settings and every other thing, settled on trying these out. Was NOT disappointed! Awesome to have some spares as well.

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.

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

Old brass extruder gear wore out quickly. Bought these and it has 0 wear to it. Buy if you need new extruder gears.

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.
