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

Installed on a Creality CR-10s. Worked like a charm and have a few extra.

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

These are *much* better than the soft brass drive gears many 3D printers come with. After a couple of clogged nozzle issues my Ender3 was not feeding correctly due to the brass gear wearing down a bit, replaced it with these and have not had the slightest issue. Great upgrade.

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

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

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

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

These are exactly what I needed and they work great

Was starting to have trouble with the extruder skipping. Replaced the stock brass gear with one of these and problem solved. Cant really speak to the durability as Ive just started a print with the new one, but the improvement in extrusion was immediate. For the money you really cant go wrong if youre not quite ready to upgrade the extruder.

Works well
