Avoid the danger of over or under-watering your plants with this self-watering planter. With a 3D printer, you can quickly make an attractive water-tight planter pot that will keep your plants healthy and fit in with your modernist aesthetic.
I looked around online at self-watering planters and came up with the design you see here. Basically, it consists of a basin that keeps standing water and a cup with a perforated bottom that stays submerged in the water. The water in the basin wicks into the potting soil keeping it moist without drowning the plant. From what I gather, roots need water but they can’t be submerged in it for too long or the plant will die. The other danger with over-watering (I’ve heard) is that it can help propagate mold and fungus, which can also kill the plant.
In my design, I created a sphere with two circular cutouts in it. A larger one holds the planter cup that snugly fits a 3” plant, and a smaller cutout is for a spout that keeps water from spilling everywhere when you fill the pot.
I designed this pot in Fusion 360 because it’s easy to create complex geometry with it and it’s a breeze for 3D printing. I printed this on a Dremel 3D Idea Builder. The Dremel file and the STLs are attached here if you want to print your own.
