As it turns out I have something called Molykote 111 compound used for lubricating the rotating valve for the Rocket Espresso Machine. Had to buy a large tube for a once every 6 month cleaning and still have lots left. Definitely food grade since it's in the hot water path. Should work great I think.
Just printed a cup with 1mm wall instead of 1.5 and random layer changes to avoid the hard spot at that location. Doesn't seem any more flexible so it may well be most of the stiffness is in the bottom part of large 1.25mm pitch teeth.
