This device couples to a standard plastic garden hose quick-connector. It should work with most brands (I've found that these things are actually pretty universal, US design is the same as in in Europe! Major surprise).
What does it do? It connects. That's all. You'll have to mod it to make something useful out of it.
I'm anxiously awaiting images of people watering their lawn with a Bre or Colbert nozzle.
And if you really want to print something that would totally warrant your ultimaker or makerbot investment, why not create a spray nozzle or sprinkler system that exactly waters the shape of your lawn.
