Can Coozie to Bottle Adapter

thingiverse

I have a couple of Ozark Trail can coozies purchased from Walmart. While they seal well when holding a can, most bottles are too narrow to seal properly. This results in drinks getting warm and annoyingly causes the bottle to flop around. Other brands with similar dimensions should also work with this adapter. I created an adapter to fix this issue. The flat side of the adapter is placed face-up on the coozie. A small lip keeps the adapter centered as you screw the ring back on, securing it in place when pushing and pulling bottles.
