Motor cover for Martian Rover

I liked the covers by Ojemine (http://www.thingiverse.com/thing:1516319) but the motors that I bought were slightly bigger and I'd used very thick power wire, so they wouldn't fit.

I redesigned the parts for a larger motor body, ducted cable routing and revised air flow to better fit my motor.

I use one M2.5 x 16mm screw with nut and anti-shake washers for the clamp.
