This is an adapter for connecting three standard 13 mm Gardena water hoses. Depending on your setup scaling may be needed for best fit.
I managed to print it on the first try in PLA, with 0,2 mm layer height and a 0,5 mm nozzle. Regarding the functionality it is waterproof and works but the part wasn't really pretty due to the bridges. Therefore I recommend printig this part with support.
