40mm Fan Bracket

thingiverse

I've got a 50mm fan on my Makergear M2 that's on its last legs, so I scrounged up a spare 40mm fan from the parts bin. Instead of shelling out cash for a new fan, I figured it was time to whip up a new bracket and get creative with the airflow. I designed a custom duct to funnel all that air down to the extruder tip, where it's most needed. Feel free to give this design a spin or hack away at it - let me know if it does the trick or if you've got any suggestions for making it even better.
