basic scale wind turbine

this is a simple scale wind turbind model, which was originally designed to fit onto a model railway scenario. There are two versions: one is approx 300mm high and fit to 1:120 scale. The other one is approx. 250mm high and fit to 1:160 scale.
The head and rotor of both versions are prepared to carry a small geared dc motor with 3mm shaft (see pictures). My personal ideal gear ratio is 1:298, then it spins quite slowly.
The 300mm version is made out of two main parts due to limited printing height of my printer. All parts are just plug and play with slight press fit.
I´ve printd the rotor just flat on the build plate with little support, whereas the surface failures are not so important.
