Self Watering Bonsai Planter with a 300ml internal capacity enough to go a week without watering your bonsai tree.

The single-piece design prints in place, no need for supports, rafts, or brims! All internal architecture is built-in.

I've also inserted rolled cotton fabric (8mm cotton string also works) into the holes to aid with the capillary effect. As the soil dries, it sucks up water from the reservoir below. See the image below for reference:
