Ender 3 S1 Bolt-on Fan Duct

thingiverse

This fan shroud bolts on to the Sprite hotend on the Ender 3 S1, with no other modifications necessary. I evaluated this cooler for cooling performance and it performed very well compared to the stock setup. Check out the [Installation Video](https://youtu.be/TrO5Q0-KEFE) for detailed performance testing towards the end. Let me know if you are interested in variations with a 5015 blower or other modifications.
