Red Bull Insulating Cover

Keeps can colder for longer

This two-piece model is intended to provide a significant, insulating air space between your can and the warm ambient air, keeping your beverage cooler for longer.

This can be achieved by eliminating infill, so that there are two walls of printed material encapsulating the air between.

INSTRUCTIONS

Print with PETG, no supports.

To maximize insulation, you may optionally print the larger part with 0% infill for layers above 6mm - layer 30 if printing at 0.2mm layer height.  Layers below 6mm, as well as the screw-top lid, were tested to work with 20% infill.
