There is a reworked one at : http://www.thingiverse.com/thing:125295 This is a derivative of Macgyver's simple lawn sprinkler. http://www.thingiverse.com/thing:30312 To increase the pressure I reduced the outlet hole size. I also created a 5 sided distribution baffle that spreads the water outward instead of just straight upward. There is now an angled entry tube from the fitting into the body of the sprinkler to allow for thick walls. To make the hose easier to connect, I replaced the screw end with a part of Jag's fittings: http://www.thingiverse.com/thing:29100 This is a quick clip of it in operation: http://www.youtube.com/watch?v=3TaY5qgqEMA&feature=youtu.be Macgyver, I hope you don't mind, I also added a set of crossed Ice-picks on the top for decoration. :)
