Adjustable Sprinkler
thingiverse
I designed this sprinkler after printing that thing at Thingiverse - http://www.thingiverse.com/thing:124253. I decided to try and improve the design so that the sprinkler sprays more uniformly from start to finish. I started over from scratch, and here's what I came up with. The screw can be adjusted to change the gap. Check out a short video of this thing in action at https://youtu.be/LjTgEJLK7b4. Note: Print that screw with 100% infill - my first one popped from water pressure because it was printed with only 20% infill. This thing was made with Tinkercad, and you can edit it online at https://www.tinkercad.com/things/acNTeO6yreQ.
