This file is the threading pattern for the male and female threading. I anticipate more people using the male threading so it is the directly usable spec, however, be aware you may need to clearance the female pattern, because it's modeled as an exact match of the other threading without clearances.

This model is not perfect and I encountered some obtuse FreeCAD problems in the attempt at making it, so if you need to change it to adjust, I've included it, but be aware that it was giving me errors that seem to derive from the spriral cuts of the threading intersecting themselves too much. I got the model to the point of a satisfactory amount of threading geometry, and moved on to other CAD.
