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

Collar is ferric stainless, actual spurs are austentic stainless. For those of you who are trying to confirm these are indeed steel via magnetism. These are indeed stainless steel. Just the spurs are austentic stainless (non magnetic) with a higher chromium content than that of the collar. Otherwise the spurs grip filament nicely.

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

I got some of these to go with a metal extruder for my Ender 3. Theyre probably strong enough to drag a refrigerator down a hallway. Get some. Throw your brass in the trash.

Super upgrade over the brass ones on the Ender 3

Bought these for my 3d printer and they work better than the stock ones! Holds the tubing well and tight! Happy with them.

Replaced the stock pulley on my Ender 3 with this one; the teeth are definitely more aggressive than the one that comes from the factory. That said, quality hasnt changed any (I ordered these after a failure that made my last pulleys teeth fill with PLA) but they are well made and work every bit as well as the stock piece. Ive heard from others that they improved extrusion issues they were experiencing, although i cant say that as I was not having issues before. Would purchase again.

used these to replace worn brass mk8 extruder gear. Working fine again, highly recommend

I was having clogs and extruder gear clicking sounds...turns out the teeth on my old gear had started to wear down. After checking my retraction settings and every other thing, settled on trying these out. Was NOT disappointed! Awesome to have some spares as well.

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!

Works great and doesnt wear out on carbon fiber
