The solution when you can't use ndis is the 1-4tang primitive (see https://www.ldraw.org/library/primref/#curv2d). Not used often because it introduces many extraneous vertices, but it solves this issue.
Otherwise your rings are BFC inverted, and you could use a single ring for the dkgrey ones with almost the same result:
