Doesn’t really say how this works
No, that’s explained in other places. This is more testing. I think he should have included a very short explanation.

Super interesting! I have a jar with a lid that I tried to scale up and the threads just fail. I wonder if I can try some overgang magic on it. 🤔
Threads should be 45 degrees to 3d print perfect but cad programs default to 60 because that’s standard for machining and injection molded screws. Use non uniform scaling to quickly change your threads from 60 to 45. (Adjust z height of just the screws by a factor of 3 ^ .5 = ~ 1.732 )
Bless you, comrade.
