Echo Flask Bottle Tether

The new Echo Flask water bottle infuses water with extra hydrogen for a variety of health benefits, but doesn't come with an easy way to carry it around. I designed a tether that slips on under the lid and does not interfere with the lid closing or the pressure seal. There are two styles. One with a small hole so you can use a carabiner or some other clip, and another with a larger big enough to grab with one finger. Print with TPU for a little bit of flex.
