I am trying to find a bottle holder than can accommodate a bottle that is 3.5 inches in diameter.

Not having any luck.

Now you do have luck!

You might look at the new TwoFish bottle holder.

It was just announced and is not on their web site yet. See
https://www.universalcycles.com/shopping/product_details.php?id=97691.
I can't find the specs anywhere so I don't know the diameter, but you
could call them https://www.twofish.biz/bike.html. You're supposed to
mount this with three cage bolts because of the extra stress so you
might want to use three of something like this
https://bbbcycling.com/en_en/bbc-110-cagefix.

Also look at the BBB Bbc-15 Fuel Tank XL. You'll have to order this from
Europe, not sold in the U.S.. See
https://www.xxcycle.com/bottle-cage-bbb-bbc-15-fuel-tank-xl,,en.php.
It isn't on the BBB web site anymore so it may have been discontinued,
but you might still be able to buy one. I have several. I use it with a
1.5L bottle that is 3.5" in diameter. The retaining device makes it very
secure, even with a larger bottle.

There are also many adjustable bottle cages. They don't work well with
larger heavier bottles.
