Drip Irrigation Screw Top Sprinkler

thingiverse

One of many iterations of a 3d printable drip sprinkler, this can be screwed all the way down to total stop the flow, or opened slightly to increase the flow. It's pretty much off or on, with only a degree or two of adjustment at my water pressure. Update 8/28/2020 - Made the flow adjustment pin wider and taller - Added better support for bridging in the cap around the first layer of threads
