A year ago now, news circulated the web of a guy who made a universal toy parts set that allowed parts from different brands to be mixed. I didn't pay much attention to 3D printing before seeing this news. I could guess that a lot of the 3D toy part designs may have come about because of this guys work. The "Universal Construction Kit" parts are on Thingiverse.
Awesome Lego model. Gizmodo has it covered.
