I was once asked if I could design a one piece sprinker that could be printed in one run with no moving parts. This little guy is an easy print. It produces a water spread of about 30' around at about 45-50 psi (local municipal water pressure). You might need to print it using a couple extra wall to prevent water intrusion into the main body of the unit (I printed mine at .2 with 3 walls, and .1 with 2 walls). I also recommend using a standard hose washer to prevent leaking around the coupling.
