Connector for DIY Rotating Sprinkler

prusaprinters

Make your own rotating sprinklers out of ½" PVC!  This connector attaches two ¾" male NPS (i.e. NPT, MPT) threaded parts.  Use a "3/4" x 1/2" Schedule 40 PVC Reducing Male Adapter" to connect to the PVC sprinkler design of your own imagination.The connector flange was built with a 15mm o-ring in mind.  I use these, with a 19mm outer diameter (OD) and 2mm cross section (CS).  A regular hose gasket will work as well, I just found it to leak a bit more.  You can also run it with no ring / gasket at all if you're OK with more of a leak in the middle.  To get the rotation make sure water is shooting out at an angle.  I suggest starting by drilling 1/16" holes and going larger only after you've confirmed you need to.  I've successfully printed this at 0.28mm, but you'll probably find the threads work better at 0.2mm.  Assembly steps:(optional) place o-ring or hose gasket over connector.Pass connector through the inside of “top”Screw connector through the outside of “bottom”.You can use this part to connect your sprinkler to your garden hose.You can see my initial sprinkler design in action in the video below.  I've got lots of other ideas, including letting the kids build their own.  Please post pictures and videos of your builds!
