While there are numerous nifty can holders on Thingiverse, I could not find one that helped insulate my drink and keep my precious Diet Dew colder longer. This functional but plain thing holds a standard 12 oz. soda can (or can of similar diameter) and helps insulate it. After using this one for a couple weeks, it seems to work as well as a foam can coolie at keeping my drinks cold.

Stay thirsty my friends...
