Custom Fan Duct for Printrbot Play Replacement Cover

I didn't like the way the recommended fan duct aligned (or more accurately didn't) with the print head, so I did a number of custom designs until I landed on one that got the airflow right where I wanted it.

Custom Fan Shroud 6 uses an angled exit opening so the shape can be a bit straighter. This is the one I use and the one in the picture.

Custom Fan Shroud 5 has the exit opening more parallel to the fan but has to shift to the side more.
