Make the wind : radiator cap

thingiverse

Hello, Here is a radiator cap whose mechanism is driven by the wind. You can fit an attachment suited for the front of your car (dependent on model). The propeller is small due to significant pressure from the road caused by the wind. I intend to build a weathervane using the same design and other mechanisms, with a larger propeller. Good print Update :-) I've uploaded a revised version of the support with holes and a foot to make a weather vane and a bigger propeller.
