This is a turbine driven sprinkler. It got it's start as a way to test 3D printed impulse turbines, but I think it's great on it's own. The turbine is a mix of Turgo and Pelton turbines and captures far more power than needed from a 1.3mm jet. The turbine spins at over 3000rpm. The turbine drives a 16 to 1 worm gear transmission to spin the deflector on the 3mm main jet. The main jet will cover a 6-9 meter radius.
Due to the size of the main jet, this sprinkler needs a solid base or stake. The clamp on stake holder is sized for one half of a 3/4" (19mm) wooden dowel rod and uses a 20mm M3 screw and nut for clamping force.
Also included in the files is a .STEP of the GHT thread and the turbine wheel. These should make it easier to re-use these parts in your own designs.
Version 1.1:
"Redirector 5.stl" is a new redirector with a better spray pattern and balanced reaction forces. Now it won't shake the stake out as fast.
