A hydroponic tower composed of a base, modules (how many do you want to add) and a top for water/nutrients distribution. The basic principle is that a pump sitting in a container, inside the base piece, pumps the water through a hose up to the top part (connected with the hose connector) and then water is distributed through the holes in the top and slides on the interior walls of the modules to water the medium/roots of the plants. The hose should be 8mm at the interior. The top part has a middle opening of D=10 mm. Works with PLA, ABS ..., basically with any FDM 3D printing material but it should be food grade plastic, safe for its destination, PLA is such a plastic.
