4Bottle Connector Wind Turbina

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/jFrldbPW9Ap
This thing was inspired by 2 bottle connector from 3d ponics.
If instead of 2 bottle connector there is 4 bottle connector and cut the bottle for the middle we get a simple wind turbina of 4 wings.
There is a center hole of 22 mm of diameter for insert a bearing of in line or skate to grant
the central axis of spinning.
The second design is another remix i made and think use minus plastic filament (conector_4botellas_final).
Better result if are raft and exterior support.
This is a in progress project an ideas are welcome.
Photos are soon to come.
