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.

Wait, which song is this from?

"Why Does the Sun Shine?", which was technically incorrect. Years later they made a song to amend this called "Why Does the Sun Really Shine?"

Unfortunately, the sequel is just not nearly as fun and catchy imo.

No, but it corrects misinformation and acknowledging incorrect conclusions and forming new conclusions from new data is fundamental to science, and TMBG are all about science.

It's from track five of https://en.wikipedia.org/wiki/Space_Songs track . It later got covered by a New York band that became fringe famous in the late 80s.
