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

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!

Worked good on my cr-10s

Works well

Replaced the stock pulley on my Ender 3 with this one; the teeth are definitely more aggressive than the one that comes from the factory. That said, quality hasnt changed any (I ordered these after a failure that made my last pulleys teeth fill with PLA) but they are well made and work every bit as well as the stock piece. Ive heard from others that they improved extrusion issues they were experiencing, although i cant say that as I was not having issues before. Would purchase again.

Works perfectly. I did not have to do anything to the estep

I have used these on every 3D printer I own or have owned. I dont even bother with stock gears anymore, as soon as I open a new printer I find the extruder and replace the brass gear with one of these. Absolutely no complaints.

Great replacement gears
