Did you ever wish to have a way to remember which can in your fridge you just put in, and which one is already cold? Now you know.
Just put your cans in a row and the marker to the left. Whenever you take out a can, take the marked can and move it to the can one position right, then replace the empty spot with a new (warm) beverage.
The snowflake symbol is not included in the STL, but rather a negative body that I added in the 3mf file. Source for the snowflake STL: https://www.printables.com/model/3907-ready-to-print-snowflakes
The author remixed this model.
