This container is designed to keep a 500 mL can cold for a longer time.
So far the fan fits perfectly, the isolation-function is in testing. Slightly thicker walls could isolate better.
Printed with 10% infill (octet for creating compartments) and 2 walls puts 95g on the balance.
edit1: First results: put 2 icecubes inside - after 1:30 h they were still visible. The 2 cubes in a cup right next to it were gone after less than 30 min.
