Overview The Creality x BEN2C Nautilus Fan Duct is an officially licensed upgrade accessory designed exclusively for the Creality K1C and K1 SE 3D printers. Developed in collaboration with renowned modder BEN2C, the nautilus-shaped air channels generate a tornado-like airflow pattern that eliminates cooling blind spots and dramatically increases heat dissipation efficiency around the hot end. The result is sharper overhangs — up to 70–75° with correct slicer settings — and a meaningful reduction in the amount of support filament your prints require. The eye of the tornado flow creates a high-speed zone directly at the nozzle tip, preventing the low-temperature bypass air that typically causes nozzle clogging. If you regularly print challenging geometries or fast-cooling filaments, this duct is a targeted, drop-in solution rather than a full hot-end rebuild.
