Hello,

I will probably use twist and flow for this (hoping I really understand the concept).
However the final fillet need to be done in Fusion.

Hello,

Actually the twist angle should be i*360 + 180 ... here's the 540 degree version.

The toroidal helix script of Michael can be modified to produce (at least some of) the cuts.
The number of turns must include fractional turns, like 1.5.
Also negative numbers may need to be entered for one or both of the two radii to get the correct handedness.
Had to run the mod script a couple of times with different +/- radii...
Well, it is late, and needs more investigation...
