Rain proof vent.

thingiverse

This is a vent I designed that can be installed on an external wall and keep driving rain out. It was printed and installed on a house boat to ventilate the fridge cavity but could be used for many applications. The idea is that there is no direct path through the vent, so any water will hit the underside of the vane and then drain down through a series of holes to the bottom and then outside. The inner vanes are higher than the outer ones so if it becomes overloaded with rain, it will overflow back out the front.
