Brass Extruder Gear for 1.75 mm Filament

This brass drive gear fits 3D printers that use 1.75 mm filament. The 40-tooth profile with deep grooves provides a secure grip on the material. It mounts on a 5 mm bore shaft and is secured with an M3 thread. The pack contains two identical gears for replacement or dual-drive setups.

Low-Friction Brass Construction

Brass material reduces friction against the filament during normal extrusion. The 11 mm outer diameter and 11 mm height keep the gear compact inside the extruder assembly. No active cooling or lubrication is required for typical printing sessions. The gear runs quietly because there are no bearings or moving surfaces beyond the filament contact.

Consistent Grip During Long Prints

Under sustained load the deep grooves maintain traction without slipping on 1.75 mm filament. Brass resists wear from continuous rotation better than softer plastics. The fixed 40-tooth geometry delivers steady feed rates for extended print jobs. Heat from the hot end does not deform the gear during prolonged use.

Questions about this item

How do I install the 5 mm bore gear on my extruder motor shaft?

Slide the gear onto the 5 mm shaft, align one of the M3 set-screw holes with the shaft flat, and tighten the grub screw firmly so the 40 teeth mesh without wobble.

What maintenance will the brass 40-tooth drive gear need over time?

Periodically brush filament dust from the deep grooves and check the M3 set screw for loosening; brass wears slowly but replace the gear if the 1.75 mm filament starts to slip.

What is the first limit that appears when printing continuously with this 11 mm diameter brass gear?

Heat creep into the brass body can soften the filament grip during long prints, causing the 40 teeth to lose traction before the motor overheats.
