That’s not what the article says, they relate it to reproducibility of the manufacturing process: “Achieving such small tip clearances is essentially at the absolute limit of what injection moulding can consistently reproduce”. Though maybe they misphrased that, as for example Lego pieces have significantly smaller tolerances and are also manufactured using injection molding.
Clearance vs tolerance is important. Clearance includes all of the things I said.
Yes, but that’s not what the article is saying.
