Windmill / Ventilator

thingiverse

This windmill/ventilator is about 21cm high (rotor excluded). I planned it as solar powered windmill, but it’s winter and the sun is hardly shining, so... It is seperated into three parts: * stand * head * rotor Three batteries and two contacts are placed in the stand, switch and electromotor are mounted in the head. The rotor is plugged onto the motor’s shaft.
