SummaryI am a very bad plant mom, and I was planning to build a closed loop soilwatering system, but that is still on my to-do list!

I remembered the trick my grandma used to provide fresh water for herchickens with an inverted bottle, and thought to do the same for ourplants.

The bottle cap comes from dpruim, which worked for me flawlessly! Thankyou. https://www.thingiverse.com/thing:3732066

Use a thick PET bottle (best are the 0.5 liter multi-use versions) which cantolerate a slight vacuum. If your country lacks the luxury of reusablebottles, try glass. You will have to experiment with the thread a little bitthen. You should only print the cap until you dial in a good fit. If it leaks, trysome PTFE tape.

For reference, my bottle is a half-liter reusable (Mehrweg) sparkling waterbottle from Germany. The thread should be the same on most bottles tho.The bottle is unmodified.

In OpenSCAD you can tweak the diameter and the height of tray, also thepipe diameter, which will determine how high the water level is in the tray.Beware that very thin pipes won't work, I'd say 6mm diameter is theminimum! Also the longer the distance between the bottle and the tray,the bigger the minimum diameter should be. (Customizer is broken, so youshould download the file and open it in OpenSCAD.)

The plant itself is not part of the model, and must be bought IRL. :/ It is aZamioculcas, if you're into that.

Prints easily. I sliced with PrusaSlicer and used 3 perimeters. Used a bit ofoverextrusion to make sure it's watertight.

The top fill pattern is Archimedean Chords, bottom fill pattern is OctagramSpiral, looks very cool in light. 5 solid bottom and top layers (each).

Seam position is set to random.
