Sorry - I had thought you were talking about another one of those vertical "longitude" pieces.

But I guess you are talking about the equator line one instead?

Yeah - that one is just barely grazing the vertical segments, it is difficult for the booleans to process intersections where surfaces kind of barely skim past each other.

If you scale that equator band either in or out by a slight amount, or use a larger sized square to sweep that particular one, it should create a slightly deeper or shallower groove which will more clearly push through the vertical surfaces instead of barely skimming along them. That kind of "clear push through" should allow the booleans to complete.

I did a quick test just now, and scaling that middle band from the origin by a scale factor of 1.01 seems to do the trick.
