Customizable Savonius wind rotor

A customizable 2-blade Savonius type wind rotor.

The parameters in the .scad file can be changed to generate the rotor you want.
The .scad file for the bearing housing and cover can be found here https://www.thingiverse.com/thing:4735770

I intended to use a M8 threaded rod to assemble the rotor. Unfortunately the hardware stores are closed during the current lockdown so I printed the shaft of the rotor slightly smaller and screwed in a bolt. Tapping in a thread will make that easier, but you can also screw in a short bolt.

The .stl files can be used with a 608 bearing and M8 threaded bolt.
