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

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

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.

I recently printed Delein with moderate success but when I switched back to TPU for a customer I noticed I was getting terrible underextrusion. Come to find out the Deleon has almost polished smooth the teeth on the brass hub. I have since replaced the brass with these and have gone through a whole spool of delrin, glow in the dark, and wood and teeth are still sharp. Highly recommend. Also the larger grub screws allow for a much tighter lock on the motor shaft.

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!

Worked good on my cr-10s

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

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.

Greatest

Works well

Im only getting about 12 hours of print time before the teeth are too warn to work. I have only used PLA. The stock brass drive gear lasted MUCH longer
