Shaker Bottle O Ring

Its an O ring for a shaker bottle! Very straight forward. Nearly every shaker bottle I've ever owned has leaked at some point or another and nearly all of them have the same dimensions. I wanted a fix and I made a fix.I'm finally tired of it and here you can see it on my GamerSupps shaker bottle, though the shape is no different from any other. I used Ataraxia Flexible PLA instead of TPU, but i don't have any particular reason for that. Both will work just fine and I believe that it is more than separated enough to be safely separated enough from the liquid to not worry about the material.EDIT: several months later, this is still doing exactly what I want it to do
