Thanks to vladua for the great wind turbine.
I enlarged the wind wheel to a diameter of 170 mm and a height of 196 mm and adapted it to my proven bearing for an 8 mm metal rod. The wind turbine parts can be put together without reworking, I only re-drilled the holes in the middle with 8 mm and then glued the parts together with CA. NabeHalter22 fits a 22mm rod, hub fits a 25mm rod or external 40mm clamps. If necessary, the axis can be fixed with M3 screws and nuts using the adjusting ring. I recommend a test print sunk in Z for the hub. Then measure the inner diameter (22.0 mm) and compensate for the possible deviation with a horizontal hole extension (Cura). Hub holder was printed with PETG and the rest with PLA.
An axle 8x310 mm and two ball bearings 608ZZ 8x22x7 mm are required, for the holder 4x cylinder head screws M5x35 with nuts.
If you want, you can glue "Savonius3klein" together and attach it to the protruding axle.
I printed all the wind turbines with PLA. I recommend brighter PLA up to 35°C air temperature. If it is warmer or if darker filament should be used, then use PETG or better ASA.
I would also like to recommend these wind turbines:
