Parametric 1/2 inch Popup Sprinkler Riser

thingiverse

I have an older lawn, which I've had to raise my popup sprinklers over time using extension risers. Unfortunately, the cheap store-bought cutoff extensions that fit over the riser keep breaking from the slightest impact of my lawn mower's wheels. This design may not be the most innovative way to use a 3D printer, but it makes for extremely durable parts. Before you can print these pipe-threaded components, download DaveGadgeteer's threading library into .scad files so you'll need to load the same directory with precompiled .stl files. Using OpenSCAD, set Length_in variable to the total length you desire and then compile the design.
