Watering bottle cap / Bouchon d'arrosage pour bouteille en plastique

thingiverse

I created this watering cap to rescue some of my trees as they were struggling due to the heat and lack of rain this summer. For many, their leaves turned brown, and they were on the brink of death. So, I made a few dozen of these small caps, and the trees were saved! This cap fits snugly into water bottles' necks (like Evian, Perrier, Cristaline, etc.). I've used several 0.5-liter bottles, many 1.5-liter ones, and some 2-liter ones that were left over, and it fits and stays perfectly on each one. This cap is designed to drill into the ground (not stones, of course) and release a few drips of water at a time (a 1.5-liter bottle takes almost two days to be emptied, approximately). If anyone wants the original design to adapt it to any other bottle size, I've made it parametric in Fusion 360. Feel free to ask!
