Camelbak Water Tracker

3D printed ring with a pointer that fits between bottle and cap and is used to keep track of how many bottles you have consumed, The ring is designed to be held captive to the bottle.
On the cap I used a label maker to print number for tracking. You could also just use a permanent marker.

The ring works with all Camelbak Eddy bottles. If the ring is difficult to turn just sand down the inside of the tabs inside the ring.

To use, just fill up your bottle, screw on the cap almost completely tight, move pointer to number that corresponds to the number you are going to drink and then tighten the cap fully.
