Looked around to see if anyone made a simple sprinkler head nozzle that sprayed 2 ways, left and right, but couldn't even find one that just screwed on to the top of a 1/2" standard irrigation pvc pipe, so I created this one. This fits a standard 1/2" npt. Not sure how long this will last but I just printed it with PETG so I'll see. You can edit the file and put holes in to make it spray 90 degree, 180 degrees, etc... And this one has it on front and back.

BTW if you are using Fusion to Design NPT hole still isn't working in the program.
