Wanhao D4S Extruder Cooling Duct

thingiverse

This is a versatile cooling duct designed to clip seamlessly over the 40mm fan of each extruder carriage, making installation and removal effortless whenever needed. No additional fans or wiring are required, streamlining your setup. Screw holes are thoughtfully included for those who prefer a more permanent solution. To ensure optimal airflow, you'll need to reverse the existing fans so they draw air over the heatsinks and blow it down through the duct. When printing this component, choose a material that can withstand some heat, as it will sit relatively close to the nozzles. A print orientation of its back side with no supports is recommended for a successful build.
