This wind turbine by Svenergy is a real nice design.
It can hold a tiny motor from toys.
Wanted to have it a bit larger, scaled it up to 200% but found the motor housing could not hold the motor i had laying around, salvaged from an old broken canon printer.
So i decided to design a new compartment that could hold the motor (19.5 mm diameter).
Be aware, this head is designed at 200% of the original scale.
If you want to print it to match the turbine of Svenergy, you need to scale it down to 50%.
The file is renamed into Wind_Turbine_adjusted_head_200.stl.
It should read Wind_Turbine_adjusted_head_200%.stl as the 200 is NOT standing for the 200mm version.
It's the 300mm version designed at 200% size of the original.
Only need a tiny bit of supports on the ring that needs to fit the standard.
