Motor Fan Mount 40mm for 1:10 RC Cars - v4

This is my project to design a fan mount for use with a 40mm fan on 1:10 RC Touring Cars. I want the mount to be able to attach securely to the fan, offer a flat surface for mounting onto the car chassis, and to duct the air from the fan onto/away from the motor.
