Mendelmax 2 PSU Fan Duct

A duct for the power supply fan on a Mendelmax 2.0 3D printer.
Normally the exhaust from the power supply fan blows directly upwards onto the underneath of the heated bed. This duct will redirect it out the side of the base of the printer.
The duct just clips into the misumi extrusion.
I couldn't work out how to print this in one piece effectively so it is in two pieces, glued together.
