About this 3D model

I needed the fan mounting holes to be a litte more sturdy, so I added two more option to the SCAD: -Define the outer diameter for the mounting holes -> More plastics, more strength -Make the bottom of the mounting holes square, to get rid of overhangs there aaand added it to Customizer for fun :-) Thanks go to iquizzle for his awesome fan mount system :-) http://www.thingiverse.com/thing:39945
