Titan Aero Fan shroud

This fan shroud is designed for a Titan Aero extruder. I tried a number of other fan shrouds but they would not print well without supports, so I designed this one to print flat on the bed without supports. Feel free to modify as needed.

It uses a standard 50mm centrifugal fan like this: https://www.amazon.com/dp/B071WMHNG5

The mount is separate and visible in the pictures See thing: https://www.thingiverse.com/thing:2943038

UPDATE (6/19/18): I modified the fan shroud to have slightly smaller diameter for both the ring and the exhaust ports. I'm getting better air pressure with v2.

UPDATE (3/17/19): I've been using v2 for a while and have been pleased with the results. However, I looked closer at the circular ring and it looks like the interior channel is constricting airflow. Version 3 has a taller ring and an 8th exhaust port. All of the other dimensions are the same.

UPDATE (8/17/19): Added a version for Creality X printers upon request.
