Servo Arm - Longer (5cm - 500mm)

Thanks to the designer for the upload :)
The arm was 350mm (3.5cm) and was to short for the setup I am using so i increased to just under 500mm (5cm). I attached to my car with 2mm x 7mm self tapping screws.
I was also going to print the servo holder. But as i was running out of filament i just drilled the holes in the original one.
14/3/17 - I have just uploaded pictures of the actual print.
