Extruder Fan Duct - Anet A8 w/ E3D

thingiverse

Bought an affordable E3D clone kit and the 30mm fan was infuriatingly loud (no surprise). I didn't have any spare 30mm fans, but a few 50mm ones were on hand, so I designed this alternative duct with supposedly better airflow around the heatsink. There is a mounting plate at the top to secure the duct, but the fit was snug enough on my printer that it wasn't necessary. Update: Credit goes to Redemptioner for suggesting major design improvements - thanks for those. Version 3 is now available with fewer and straight vanes. Also 2 options are available - with and without the mounting tag so users can add their own mount point according to their setup.
