Windmill - with working gear

thingiverse

It's printed in rich brown PLA on a Monoprice Select Mini with an E3D V6. I based my design on two images of Dutch windmills, but the crucial feature for me was that the moving sails would turn a gear inside the mill. Unfortunately, I still haven't found a use for this feature - perhaps turning an LED candle or pumping water someday. The windmill does serve as a garden prop, with rotating sails driven by the wind.
