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

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 enders part

The angle between the two position screws are closer to 45-60 degrees.

Got these for the ender 3 extruder they work much better than the brass ones that came on it.

Filament is the natural prey of a 3d printer, and a printer with a brass feed gear will inevitably starve to death as the teeth wear down, I refit mine with these stainless steel gears, which contain many more teeth and grip better than the standard brass ones. Now the filament in my boxes tremble in fear at the newly terrifying maw of my printers.

Good nuff

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

Better than OEM.

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.

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