Nema 17 cooler for 50mm fan

This shroud clips over a NEMA 17 motor and directs the air from a 50mm fan over the motor to cool it. No changes to the motor are required and it is retained by friction alone.

I use a quiet fan but will be using a resistor to drop the speed a bit as it is very effective.

It was designed in DesignSpark and is an original idea, not based on any other work.
