This Can Cozy snugly fits a standard 355ml/12oz can, creating a small pocket of air to insulate it. Keeping a cozy on your favorite beverage helps keep it cool, and stops your hand from getting wet from condensation.

I've printed it in PLA, PETG and TPU. All work fine but TPU does feel a little flimsy, so I'd stick with PLA for overall cost effectiveness, or PETG for longevity.
