I'm working on a wind farm and have put together a model of a Vestas wind turbine, not exactly to scale, but as best as i can do by eye. The blades are a scaled version of the amazing ones from St3rz0, and the whole thing is inspired by utility scale turbine from OpenSourceClassroom. It will need some sticking together, either with superglue or plastic soldering. For the hub spindle there is a 3mm hole in the centre of the hub, I've used a nail hot glued into the hub.
the blades will need some support structure, as will the wing on the nacelle.
This is my first attempt at designing anything, so go easy on me!
