MakerGear M2 Ducted Fan Mount by profhankd

Last crawled date: 3 years ago

There are a lot of alternative hot-end fan mounts for the MakerGear M2 that try to increase airflow where it counts, but most of them require a modified mounting assembly for the hot end. This one goes on just like the standard mount -- in front, and is still able to pivot out of the way for access.
As of May 12, 2015, there's now a second, more aggressive, version with a rectangular output. You can see the difference in the third image. The more aggressive version tends to cause uneven cooling on larger objects, so I don't recommend it unless you're printing things with very thin structures.
As of March 7, 2016, there's now a third version that aims the air flow just about perfectly. It's got an oval opening like the first version, but it points more directly where we want the air, and that works -- even better than the second version, which appears to suffer pressure loss from using a rectangular opening. The catch is that this 3rd version still doesn't produce perfectly even flow because the air is all coming from one side. Still, it is better than the other two versions....
