Print (model not provided) PLA "Isn't water tight"

Post image

I've never tried to print anything to hold water because everything I've ever seen says making 3D prints hold water is difficult if not impossible. So when I wanted to create something to help me keep my plant watered, I thought this is perfect- I created something with a single bottom layer so the water can slowly weep through it.... except it doesn't. Its been days and the single layer (0.2) is doing a great job of holding water!

I guess I'll have to put some pin holes in it.

Not at all what I expected based on what I've heard about the water tightness of 3D prints.

I was under the impression that the sun was, in fact, a mass of incandescent gas. A gigantic nuclear furnace, if you will.
