About this 3D model
Remixed from http://www.thingiverse.com/thing:45930 Topology optimization with topy: https://code.google.com/p/topy/ Video of the optimization process: http://youtu.be/LTsEBuIUHTA Updated: dxf and scad files, smoothed and thresholded to get a nicer part. I like the quick release version by mrwolfe too, so I added an stl in that style.
