Vertical wind turbine

For hoverboard engine 350w upgrade

I am at the stage where I am printing blade in different positions and setups and I amd trying to eliminate mistakes (check uploaded pictures) and to make most officiant way.
At the moment only in pla material to find best result and the I will move on to other stronger and slexible materials.

OBS: I found the blade to be quite weak or little bit too flexible that is why I also start to experiment with some reinforcements.

Throw me some feedbacks if you have printed and got some successes..

more info comming...
