Plant watering

thingiverse

Hi everybody! I'm using these plant waterings a lot here: https://www.amazon.com/Blumat-3-Piece-Irrigation/dp/B0001IOZ98/ref=sr_1_5?ie=UTF8&qid=1534070617&sr=8-5&keywords=blumat+irrigation However, some of them don't work as they should. So I had to come up with a solution. I looked at the standard screw caps on PET bottles and created my own version. Most bottles fit perfectly, but some have slightly bigger tolerances and aren't tight enough. Good luck and have fun!
