About this model

This is a remix of Tinymachines' fan duct from their Super Upgrade files. It hopefully give a little more even airflow. I also added a guided channel inside the fan so that some air is guaranteed to reach the outer parts of the duct. In addition, I lengthened the screw mount pillars so that it can sit a little lower and avoid the hotend cover. There is still ample clearance for the nozzle so it doesn't sit dangerously low. Also, sorry for the large file size. I didn't have the original CAD files so this is a hack job using a volume modeler in C4D. As such, there are many polygons.
