Plant watering

thingiverse

Hi everybody! I use many of these plant waterings here: https://www.amazon.de/Blumat-3Er-Satz-Bew%C3%A4sserung/dp/B0001IOZ98/ref=sr_1_5?ie=UTF8&qid=1534070617&sr=8-5&keywords=blumat+bew%C3%A4sserung However, some do not work as they should. So a solution had to come from. I looked at the standard screw caps of PET bottles and made my own version. Most bottles fit. Some bottles obviously have slightly bigger tolerances and are not tight. Good luck and have fun!
