Description
Second iteration of the Vertical Wind turbine.
There is a new version of this design, that has much promise.
thingiverse.com/thing:15083
In order to get the design greener, the blades have been hollowed out in order save on plastic. Added M8 nut recesses in order to couple the turbine to a M8 threaded rod. The rod serves as a bearing carrier and drive shaft to the generator.
Added STLs

Instructions
The code depends on the Parametric NACA4 library (thing:12634) or the condensed version of it by levincoolxyz (thing:14179). Rename whichever version you use to naca4.scad and drop it in the same folder as the source.
Print a top and base section, and add 2 + 3n atomic section in order to keep the turbine constant torque.
Stack the printer sections. Gluing optional. Insert m8 rod through the center axis and tighten the stack using m8 nuts. Rotate the top and base sections to tighten. Thread some filament through the blades to connect them. Glue is optional.
To fix the turbine to the rod, lock it into place by tightening additional M8 nuts onto the ends of the turbine.
If the turbine is short enough it will be possible to support it from one set of bearings on the same side as the generator, allowing a free standing turbine.
Charge your deep cycle batteries with a couple of these, and free yourself from the clutches of the carbon intensive power companies...

The new model doesn't skein well at all... the toolhead movement becomes non-continuous on the perimeter. A better option (trying now) would be to use the older version, with low infill to keep the weight down.
I'm trying this now - perhaps with some steel cable tension-wound through those little holes.

Has anyone actually printed and run this design? or even the original?

This is one of the reasons I daydream of building a larger RepRap and to find out how well the whole "PLA-as-lost-wax-mould-casting-aluminium"-thing works. (It aught to work just Fine!)
