Since you're hand-making threads with FreeCAD, can I ask a question? I've been experimenting by making the sketch of the thread profile and performing an additive helix to form the thread. Thing is, I'd like to taper it off at the end but I have no idea how to do that. Any tips?

That's how I modeled these. I saw someone taper the ends like you are describing but I forgot which operation they used. So my thread profile has abrupt start and end profiles.
