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

I bought these to replace the one that came with my Anet A8 extruder and it works great! Way better than the one that came with my printer with less than 24 teeth.

These are nice fit my ender 3. I do recommend adding some loctite to the set scew or it will come loose everytime

Purchased BIQU Extruder Pulley 36Teeth Bore 5mm Stainless Steel Drive Gear for 1.75mm & 3mm 3D Printer Filament (Pack of 5pcs) for 3D printer upgrade. Gears are made of high-quality stainless steel and are a direct fit replacement for Flashforge Adventurer Series 3D printers. Highly recommended!

These work great in my ender 3

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

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

Good nuff

Fit perfect and worked great after e-step calibration on cr-10s.

I ordered these to swap out the stock grear from my Ender 3 and they seem to be a good value upgrade. They are all well machined and have two grub screws. These are a bit more aggressive than the stock gear but thats what I was looking for.

Definetley doesn’t grind my gears the least bit. Works as they should.
