Creating a Functional Watering System Inspired by Dunes Thumper. I recently watched Dune: Part Two and was captivated by the iconic Thumper. Inspired by its design, I decided to create a functional 3D-printed replica with a twist: my Thumper serves as a unique watering system! Heres how it works: Body: Acts as the water reservoir. Spike: Inserted into the ground, it has holes to diffuse water. Top Part: Floats on the water, indicating the water level inside the Thumper. Im really proud of how this project turned out and I hope you find it as cool as I do.
