Can Koozie

by Jon

Simple one wall design can koozie. The idea is that the less plastic that is touching the can the better it will be insulated as air has a lower thermal conductivity.  It has fairly tight tolerances to keep the air in the pocket isolated to improve insulation futher.  There is a hole at the bottom to push out any cans that get stuck. The single wall design also saves on material. Validation I printed out the 473 ml design  24 times for a beer advent calendar and seems to work well with most brands. The other sizes are untested but should work, based on my measurements.  Customization I've included the FreeCad file in case adjustments are required,  and would be willing to add more sizes if you provide the measurements.
