About this 3D model

This is a small 3D printable hydroponics system. It requires a small water pump and a tube to pump water through. Warning: The water reservoir might need coating with something waterproof, such as epoxy. PLA generally leaks after a while. I also coated the water channels and the swimmer with epoxy. The idea is that the reservoir holds a nutrient solution (look for hydroponic nutrients), which gets pumped up with a small waterpump. The nutrient solution then flows along the water channel. A plant holder on top places the roots of the plants in the water channel. For that, I wrap the stems of the plant in foam rubber, so that they sit firmly in the holes. You can see the pump that I use in the pictures. A video of the build is available here: https://youtu.be/2em0Q3HlyuI
