Wind Turbine Hub

thingiverse

I fly RC helicopters, and therefore have a few broken Rotor blades, and i have always wanted to do something with the old ones. With the advent of my 3D printer i now can, and this is a model of recycling these perfectly formed aero foiled blades into a wind turbine. This is the HUB and there is also the nose cone to complete it, the blades are set at a 30Degree angle, and can be connected directly to a stepper motor, or via a belt to another generator device.
