Funny how easy it is to make the world a better place. Even for something as simple as a rain catcher. The concept has already moved to the 3D draft. When I find a moment of free time, I will refine the model, and when the filament arrives, I will create the first prototype. And maybe even for fun, I'll file a patent application. Yes, there are many patents for this type of design. Either way, mine will be the best and most effective of course :)
