Hot End Fan Duct
thingiverse
Fan started making a grinding noise after second print, Googled to find out its because fine strands of filament get sucked in. Made this simple duct to prevent it from happening again. I also believe it helps with cooling since it is no longer pulling hot air off the bed. Version 2: is more rounded out with a little more area for more airflow. Version 3: Easter special Version 4: Narwhal Version 5: The "Richard" adds a fan silencer that seems to increase air velocity as well reduce noise The original silencer here https://www.thingiverse.com/thing:3597687
