Youtuber 3DPrintedLife made an informative video showing the wind turbine he designed and printed. He went all out with the features, replicating full size wind turbines by adding variable pitch blades, on board wind measuring station and a fully custom PCB for controlling the power generated.

The files are open source and available to recreate your own.
