I keep my dog hydrated
I designed it especially to operate with 16.9oz Poland Spring bottles - one of the more omnipresent water bottles around in my neck of the woods.
The paw prints keep it from rolling around when set down, while using it, but I generally hold it in my hand. In order that folks understand it is the dog's bottle, I contained a variation with no paw prints along with a small coordinated cap.
It's possible for you to run a cord (I used a shoelace) through both holes as a shoulder strap which also helps keep the bottle in closely.
The build took 2:40 on a Replicator2 with supports and .30millimeter layers.
The underside side could use a bit of sanding since the build uses supports.
