Ren NPT 3/4 inch!

After stubbornly refusing to make the attempt, I finally succeeded in modeling ¾ inch NPT threads. This model can server as a plug for a ¾ inch PVC threaded female adapter. But it is generally useless on its own.

What it does represent, however, is the result of several attempts to create an accurate model in Rhino3D. Yay!

Could not have done it without the measurements and information found here: https://www.sparxeng.com/blog/hardware/how-to-model-npt-threads-in-solidworks

Note: Why make it myself instead of using one of the several excellent models already out there? 

• Unclear or undesirable licenses. I do not begrudge any designer the right to set the terms of how their work is used. I just wanted freedom to do as I wished. I also decided to make my model available with an open license.

• Practice. I really didn't want to do this, but the practice will let me doing better and more complex future designs.

• I wanted a Rhino3D native model rather than converting an STL/3MF and having an overly complex model to work with.
