The Stansport is 2.820" (71.5mm) and the Cal Bike Gear is 2.885"
(73.3mm). Even worse is that the indentation ring is off by about
0.300". How can this happen? In medical, aerospace or other electronics
we'd get flogged for that.

There is no standards body for water bottles. The diameter is supposed
to be 2.875" (73mm) with the indentation on tall bottles at 5.0" (127mm).

You should write a letter to Stansport. Maybe consider contacting an
attorney about a class action lawsuit. Claim that the bottle bounced out
on a trail and a mountain lion took it. Jay can handle the lawsuit for you.

I can also wrap some sort of bungee cord around it, hobo-style. However,
that gets old and the bottle won't go back in easily without pushing the
bungee down.

Use layers of heat shrink tubing until you get that extra 1.5mm or so.
Of course that size heat shrink tubing will likely cost more than just
buying a proper bottle.
