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

The original extruder pulley that came with my 3D printer wore out very quickly. Replaced with this & works great. No more filament slipping.

quick fix to my extrusion problems!

perfect last Way longer than the brass ones buy one pack and they will last a long time

Slightly smaller than standard for my CR-10. Needed to play around with the feed rates to get the right flow. Dramatically less feed slippage though, and Im assuming the steel will be more durable than the stock brass parts.

Perfect fit to replace the worn brass part on my jgaurora A5S.

Worked good on my cr-10s

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!

Actually Im testing in my CR-10, in this short time I dont have any problem

Fit perfectly on my creality cr-10 mini. Still waiting to to see the durability.

Works very well, definitely an upgrade from the brass. And fits my JG Maker Magic printer.
