gravity water valve
thingiverse
A clever water valve, powered by a pump, halts the flow of water due to gravity when the pump is inactive. I'm utilizing it for my flowers while on holiday, thanks to an Arduino setup. To assemble, simply insert a steel ball (10-12.5mm in diameter) between the two parts and connect the hose. Since I printed with a 0.8 nozzle size, there was some leakage, so I added tape to compensate.
