Make the wind : radiator cap

Hello,

Here a radiator cap whose mechanism is actuated by the wind.

You can fit a holder adapted for the front of your car (depending on model ...)
The propeller is small because the wind causes a significant pressure on the road.

I plan to make a weathervane on the same model and with other mechanisms and with a bigger propeller.

Good print

Update :-) I posted a new version of the support with holes and a foot to make a weather vane and a larger propeller
