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

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!

Better than enders part

I like these a lot better than the brass ones that the Ender 3 comes with. They seem a lot more durable and grip pretty well. I dont think Ill have to replace one of these for a long time.

Using this drive gear to grip a brass rod. Nice. Set screws hold tight on extruder shaft. Used a standard allan wrench. Its loose in hex socket, too much force will round the hex.

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 seem like they will hold up better than the brass. They have two set screws and were an exact replacement for what I had.

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.

They seem to last better, but the teeth arent very sharp so they dont grip very well. At least, compared to the brass ones that came on my printer.

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

Super upgrade over the brass ones on the Ender 3
