I tried planting some sunflower and green bean seeds in some small plastic cups indoor to start them for later planting, and there was no drainage in the cups so mold started growing on the top of the dirt so I hopped on Thingiverse and modeled this plant starter to hold little cups for each plant with holes in them to drain the excess water into the holder below so there would be no mold. I made a couple different ones with the names of the plant on the side so i wouldn't forget which one is which. I also put a blank cup so you could put whatever plant name on it you wanted or if you wanted to just write on it. I took a sharpie and rubbed it over the letters so it would be easier to read it and give it a nice touch.
I printed the base at 200% and the pots at 180%
