A can Koozie for 500ml Monster Energy(or same sized cans). A full can should slide gently into the koozie when dropped in, while an empty can should hold in the koozie until pulled out.
When empty the Koozie is relatively strong, but don't squeeze it too hard. When the can is inside it's quite a bit stronger/sturdier(as something like this should be).
0.3mm layer height.
The author remixed this model.
