All-Metal Extruder Upgrade for Ender and CR-10

This gray aluminum alloy extruder replaces the stock plastic feeder on Ender-3 series and CR-10 series printers. The sandblasted and oxidized finish resists cracking and wear for more reliable long-term filament feeding. The kit includes all necessary screws and parts for a direct DIY installation without changing the stepper motor.

Adjustable Tension and 40-Tooth Drive Gear

A built-in adjustment bolt lets you tune idler pressure to match different filaments and printing conditions for consistent grip. The 40-tooth drive gear provides a stronger, more positive bite on 1.75mm filament. This combination helps prevent under-extrusion and improves feed stability across common materials including PLA, ABS, PETG, TPU and wood-filled filament.

Smoother Filament Path and Compact Package

A beveled filament entry reduces scraping as filament enters the feeder, supporting cleaner and steadier extrusion into the hotend. The assembled unit measures 11 x 8 x 6.5 centimeters and weighs 68 grams. The package dimensions are 110 x 80 x 65 millimeters with a weight of 175 grams.

Questions about this item

How do I install the extruder on an Ender-3 V2 and which step is often missed?

Mount the supplied aluminium body using the included screws; the step many skip is tightening the idler-tension bolt until the 40-tooth gear grips the 1.75 mm filament without slipping.

What part will need replacement after extended printing?

The 40-tooth drive gear will eventually wear and should be swapped when filament bite becomes inconsistent.

What limit appears first during a long, continuous print?

Heat soak in the aluminium body can soften PLA inside the feeder, so monitor extrusion consistency on jobs that run for many hours.
