This tiny item fits snugly into the end of 1/4" irrigation tubing, and splits the stream in two. My intent was to reduce the speed of the water as it exited, and also spread out the area where water is directed. It prints with the holes at the top, and doesn't need any support. It's quite small, so if you have problems with bed adhesion you might need to add a raft. I printed about half a dozen in white PLA with no issues. My water is delivered through a siphon, so there is almost no pressure; this item is best suited for a low-pressure drip-type system, not directly off of a city water line.

Printed in white PLA at 230 degrees, sticking to painters tape on an unheated bed. I printed at 100% fill because I wanted it to be water-tight.
