1/2 PVC threaded nut

thingiverse

Nut for threaded PVC. This one is for half inch. I set the thread pitch at 1.8, which approximates 14 TPI close enough. It fits threaded riser pipe for sprinklers which are available in many short lengths for building small-ish things from 1- 4 feet in size. It also fits the various threaded PVC connectors. You can find a table of thread pitches and outside diameter for many PVC sizes here:http://www.harvel.com/technical-support-center/dimensions-pressure-ratings/pvc-and-cpvc-threaded-pipe You can convert SAE to metric thread pitches here: http://mdmetric.com/tech/tict.htm 3/4 inch would also use 1.8 on the thread pitch as it uses the same thread. The file could probably be trimmed down considerably by using a higher resolution number.
