Rain Power Generator

This is an educational project I made and published on YouTube. It shows how much rain power (watts) is available from a residential rooftop and the best way to harvest that energy. Most of the parts are 3D printed from a CAD model I made in Fusion 360 which is included in this post. I did some machining and welding but I've seen others get away with all 3D printed parts or substituting with wood if necessary.
