I've just tried your approach but with the first two layers. It worked nicely. I didn't use the aligning rings because I exported the part and the inlay in the single .step file. PrusaSlicer sees two separate bodies in the step file and they are perfectly aligned. I can disable one body at a time just by setting its type to "negative volume".
Yes, now that PrusaSlicer can directly import step files the registration rings aren't necessary. When I developed the technique for my own use, that wasn't an option. Of course, they may still be useful for people wanting to use a different slicer. I may do a follow-up about using step files.
There is a "rounded rectangle" tool in the dropdown of the rectangle tool. You can also use symmetry on the center of the fillets to constrain the center to the origin.
Thanks. Very thorough explanation of the process. I've never seen this trick before.

Good point about the center of the arcs. I've gotten in the habit of using the regular rectangle, the rounded rectangle is fairly recent.
