This model was created as a functional design for my final exam in 3D printing. The design is a bell siphon—a device used in hydroponics to control water levels. Hydroponics grows plants without soil, using water and nutrients. It saves space, conserves water, and produces healthier plants. Popular hydroponic crops include lettuce, herbs, tomatoes, and peppers. It's a space-efficient way to increase food production. And therefore it should be a free part for everybody with a 3D printer!
