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

Perfect replacement for sender 3v2. Old brass piece was worn out from clogs but this get it back up and going in no time. Will need to adjust esteps.

quick fix to my extrusion problems!

They work great the higher teeth count eliminates grinding.

A vast improvement over my stock brass gears. If you are having extruder issues, this is well worth a try to fix the problem. Used on a stock Ender 3 extruder, and I had no need to change e-steps (checked before and after, same result). YMMV, but this fixed my under extrusion.

These work great in my ender 3

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!

Better than enders part

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.

These are *much* better than the soft brass drive gears many 3D printers come with. After a couple of clogged nozzle issues my Ender3 was not feeding correctly due to the brass gear wearing down a bit, replaced it with these and have not had the slightest issue. Great upgrade.

The original that came with the printer is too cheap and bad. My printer stopped extruding everytime because of them. With these my problem went away. I replace them in an Ender 3 v2
