The Knuckle Thread - Any Thread Profile? - 3D printing

[BallBearing]

"Knuckle threads are an unusual highly rounded thread form" ( Wikipedia). Probably the Spirix plug-in way is the fastest way to do custom screw threads "manually". On the first video (Follow Me And Keep plug-in) I close the thread ends with the Curviloft. Perhaps there is some nicer way?

These videos can give you some clue how to do the Edison thread (shallower) or any thread profile you need.

P.S. Quite late, I noticed Jim Hamilton's nice Spirix plugin. But the Follow Me And Keep I have tested on older SU versions to work ok.
