A6 Fan Duct Modified

This is a slight modification of Nick Rimmer's Fan duct. I slanted the top to reduce howling and optimize airflow. I also made the fan's top dimensions larger since the original fan duct fell out on me during printing and damaged my 50MM fan. This print should make your fan duct a nice tight fit and keep it from falling out, possibly damaging your fan and/or your print. If you like the original fan but not the howling, this item is for YOU!

There are better fans ducts out there, but this is the "ideal" fan duct that should have been provided by ANET from the factory with the printer. It is basic, sized correctly, provides adequate cooling, and doesn't howl like the wolves.

If you're looking for a more sophisticated fan duct, consider one of my other ones:
