Enhanced Cooling Duct for Creality Ender 3 – 4015 Blower Fan MountDescription:

This is an upgraded cooling duct system designed specifically for the Creality Ender 3 series 3D printers. Its primary goal is to improve print quality through more efficient and evenly distributed airflow, especially during the printing of overhangs and fine details.The system consists of two parts:

The main body, which is securely attached to the printhead using screws(flat head screws required);The secondary duct, which clicks into place via snap-fit joints — no additional screws required.

Designed for a 4015 radial (blower-type) fan, this model features a dedicated mounting slot that holds the fan precisely in position without extra hardware. The compact geometry ensures minimal distance from the hotend, delivering improved and focused cooling directly to the printed model.Benefits:Improved airflow direction and efficiency;Enhanced print quality with cleaner bridging and sharper details;Non-intrusive design – does not interfere with the printer’s moving parts or visibility;Modular design – easy to modify or upgrade.

Notes:Files are provided in STL format and can be freely customized or adapted to suit your specific needs.Recommended to print in PETG or ABS/ASA for heat resistance near the hotend.Model tested virtually and designed with practicality in mind.
