Plant Pot

thingiverse

You'll want a simple plant pot that lets excess water flow into a side reservoir and evaporate out the top. This one's designed to fit little planter pots from Walmart, so if you get one of those, no need for pottting. This design can be printed upside down without supports. I've also included screenshots for printing in multiple colors, just in case. Here's how you can do it using Cura as a slicer and its "pause at height" setting.
