About this 3D model

Derived from http://www.thingiverse.com/thing:24282 I just removed the hand cranck, gears, bearing and replaced the parts with a brushless motor I had from a T-rex 450. There should probably be some sort of feet for mounting it on a surface, but that is up to you! It is quite loud! So mind your neighbour :) Edit 20/3/2013: New impeller unit with screw for fixating the wheel on the axis of the motor.
