I didn't like any of the hand planters on thingiverse/yeggi, so I made my own! Optimal thin pot with drainage, with only minimal supports needed for the drainage overhang part. The weight is somewhat unbalanced, so I recommend adding sand to the base while it's printing in order to give it some additional weight to counter the soil/plant center of gravity. Great for succulents!
