XL Self-Watering Planter that maximizes the build volume of the CR-10.

I wanted something larger and more modern than existing designs I could find for self-watering planters, but also wanted to minimize the plastic usage. Therefore, I designed this from scratch to work as a self-watering planter without being quite so obvious. The basic design is inspired by https://www.thingiverse.com/thing:3647029, but is a completely new design in Fusion 360. The side of the top pot has a recess to allow for watering, but the cutout is also printable to hide the hole and prevent evaporation.

I printed this with a 0.8mm nozzle with 1.2mm extrusion on the outer pot for strength and to make it waterproof. I used 0.8mm extrusion for the top. I printed the bottom in PETG, but the top warped, so I reprinted it in PLA. All of these files were printed in vase mode, but if you have a smaller nozzle, you could just increase the number of external perimeters, disable infill and use 0 top layers, to achieve the same result. There is 1.6mm between the top and bottom outer walls, so with 1.2mm walls on the bottom, you still have a 0.4mm tollerance. That means this can also be scaled down if you like the design, but want something smaller.

The print used 400g of plastic for the bottom and 300g of plastic for the top. It is watertight, but just to be sure, I also sealed the bottom with waterproof wood glue. The nubs in the bottom of the top piece need to be drilled out to allow water to enter the bottom and absorb up into your soil. It holds about 2 liters of water before you reach the base of the funnel.
