Tired of the notorious stock Creality extruder arm snapping mid-print and ruining your 14-hour print? This drop-in replacement is redesigned from the ground up with reinforced stress points, thick walls, and optimized geometry to deliver reliable, long-term grip without flexing.
Whether you're fixing a broken stock arm or upgrading proactively, this print saves you from buying an all-metal kit while giving you butter-smooth filament feeding.
Why Print This Upgrade?
Beefed-up Pivot & Tension Points: Thickened critical areas where the stock arm always fractures under spring pressure.
100% Drop-in Fit: Works seamlessly with your stock Creality stepper motor, brass gear, bearing, and spring.
Zero Flex Geometry: Rigidity equals consistent pressure, preventing under-extrusion and filament slip.
Cost-Effective Fix: Costs pennies in filament and installs in under 10 minutes.
Assembly Tips
Remove your old arm and transfer the stock bearing over.
Don't overtension the pivot screw—it should move smoothly without side-to-side wobble.
