About this 3D model

I like the design of binaryconstruct http://www.thingiverse.com/thing:26779 but the Corsair fans have a different (smaller) gap. I have completely rebuilt the holder with Sketchup. The fan has 63.47 CFM at 30dBA. I have two of them running (one on each side) with this controller: http://www.thingiverse.com/thing:22202
