My family noticed that leaves from the tree in our backyard were often clogging up the drain during rainstorms, leading to potential flooding, and they called on me to figure out a solution! My dad suggested making a domed drain cover - also known as a beehive drain cover - so that even when leaves were washed next to it, they wouldn’t be on top to block the water flow. After a couple of mock-ups and some quick CAD modelling, I came up with this design, which I tried to make somewhat aesthetically nice as well as effective. I was a bit apprehensive about making it out of plastic at first, but it’s solid enough to stomp on and has held up surprisingly well since it was put in. Maybe it’s a simple project in the grand scheme of things, but I haven’t done that many real-life engineering projects like this before and I think it’s a pretty good first step.
