Flowerpot, has a water reservoir (self-watering). Hexagon shape for space saving, print many and fit them close together. Easy peasy print. Don't use any supports. Just a simple hexagon shape, enjoy. Default size is a 5-1/2 hour print on my K2 plus, approximately size 150mm diameter and 150mm height.
I'm terrible at watering plants. Always over or under watering them. With this, I can look in the water reservoir, and fill the water level to about 50% of the soil height, never overwatering my plants and ensuring there is always some water inside to keep the soil moist.
