American Red cup Kratky system

Update 2020/06/23 Adding a rockwool_pebbles_pod.stl file, which is basically the same as the previous rockwool_pod.stl but now you can put some clay pebbles at the top to keep the plant straight. I noticed it was necessary after some time. Use the american party red cups to grow vegetables! I'm using Kirkland "the big red cup" ones. It's a typical kratky setup, simply fill the cup 3/4 with nutrient water. It's in two parts, one is for holding a 30x30x30 rockwool cube and the other part is the actual lid. Everything prints without supports. The lid_standard_pot.stl design is to be used with the standard pots from this project: https://www.thingiverse.com/thing:3405964 Which is quite handy as you can directly start your seedling in the red cups, let the roots grow and when it's ready you can put the pot inside your grow tower.
