Red Aluminium Extruder Kit 1.75 mm Filament

The LONGER red aluminium extruder kit replaces the stock plastic feeder on compatible 3D printers. It accepts 1.75 mm filament and includes the aluminium MK8 frame, brass drive gear, spring, bushing, Bowden fitting and mounting screws for a complete DIY upgrade.

Check printer compatibility and assembly readiness

Verify that your printer uses a Bowden-style extruder with an MK8 mounting pattern before ordering. The kit arrives unassembled, so you will need basic hand tools and the ability to follow a mechanical build guide to install it correctly.

Suits owners wanting stronger filament grip

Makers who experience slipping or grinding with the original plastic extruder will benefit from the all-metal construction and improved drive pressure. Users with direct-drive printers or non-MK8 mounting patterns should look for a different upgrade kit.
