I dig it, it can hold about a cup of water and it does seem to slow drip, though I didnt attempt to clear the tiny hole as I want it as slow as possible. I needed to print with supports (tree default) at 31 degrees for increased success rate (it wastes some filament but I think it's worth it for a bigger print like this). I also like I could scale it up or down a bit as needed. The default size is quite good for a plant in a 5gal bucket or pot in my opinion just to keep the roots a bit moist.
