This Helical Wind Turbine needs a little more wind to get moving, but then it goes for it! The rotating part is supported on a narrow ring, which keeps friction to a minimum. Print in Place for the rotating part. The base (or wall mounting) is provided by a slightly tapered square pin that secures itself.
I recommend printing in PETG or higher quality material to withstand heat from direct sunlight. If you want to print in PLA, choose a light color to reduce heating.
Printed 0.4 nozzle, 0.2 layerheight.
Paint on tree support on the back tip of the blades. 5mm brim.
