Awesome! I was just looking wow I was wrong 90° or adjustable seem to be the most common sizes lmao. 
. Also just thought of another idea if possible. Air pots seem to be pretty good but way to big for 3d printer I’d think unless you had a big printer. How about @Pigeonman “speed cups” they are solo cups with holes drilled all the way up. Solo cups aren’t very sturdy so only couple of uses and labor into cup. What if 3d printed seedling air pot. Also would be great for solo cup grows. Since you can make the holder figured big enough to make cup. Idk just thinking of things cause that’s how my brain works. I’ll find a pic and post it. Also idk if you design your own templates or have to find one to download. Anyways thank you I have seedlings and seeds just starting so will be perfect timing for some lst. One of the first pics you can see what I mean.
