This project is a ‘branch’ of https://www.printables.com/model/78572-self-watering-rectangular-planter-with-clipping-sy which is a ‘fork’ of https://www.printables.com/model/57885-self-watering-rectangular-planter-with-optional-la and my motivation is to have not only a syphon where the water and earth do not touch directly, but an alternative siphon with an i, which also has a solid base, to catch any soil falling into the siphon, and to hold it up as you withdraw the inner pot from the outer pot - with the hope of less soil creeping into the water

The model is solid at the bottom but you may do as I did and choose no bottom or top layers and use infill of your choice to further moisten your bottom.
