Creality Ender 5 / Micro Swiss Hotend Fan Duct

thingiverse

This hotend fan duct is designed specifically for the Micro Swiss hotend used in Creality Ender 5 and compatible printers with stock hotend shroud. It prevents the hotend cooling fan from blowing directly onto the heater block, instead directing 100% of airflow through the hotend heatsink. The duct snaps over the front fan inside the hotend shroud, but you'll need to remove the upper left screw holding the side fan in place temporarily until it's securely snapped into position. Once in place, re-tighten the screw and it will hold the duct firmly. When properly fitted, make sure the heater block insulator doesn't come into contact with the duct. To ensure this, print the duct from a heat-resistant material like polycarbonate to prevent warping or melting near the heater block.
