Creality SP CFS Hub Idler Pulley Assembly

Precision pulley used in the filament routing system of Creality’s CFS (Color Filament System). It helps guide and direct filament movement between spools and the extruder hub, ensuring smooth transitions and reducing friction during color swaps. Designed for durability, the pulley maintains accurate filament alignment, minimizing deviation and print artifacts during multi-color printing.
