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 inspired by bucket wheel turbine designs that pre-dated the Pelton turbine and captures far more power than needed from a 1.3mm jet. The turbine spins at over 3000rpm and makes a hi-tech whirring sound. The turbine drives a 64 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.

Print one copy of each .stl and assemble as shown in the photos. Printed with a 0.4mm nozzle, 3 perimeters and 6 top and bottom layers. Must be able to print 45 degree overhangs and string all the way across bridges. The feed holes to the jets are bridged right off the printer and need to be cut them open. All parts should spin freely with minimal friction. The snap ring goes on with the champhered edge up. Otherwise it won't seat properly in the grov
