Soup cooler - Suppenkühler

thingiverse

It's a soup cooler, something the world doesn't need. The idea came up when my son didn't want to eat his too hot soup - I don't like it either. Since I have lots of fans, 3D printers and a power bank, I thought, why not? It's an 80mm / 12V fan... the power bank only delivers 5V - the fan is slow which isn't as efficient as 12V, but safer and easier to use for the kids. It's probably more placebo effect (because of the 5V) but the soup is colder and tastes better after using it (according to my kids) and I have to print one more because they always argue who can use the thing first. P.S. My power bank has 4 USB ports... I will solder a second USB cable to the fan - which should then run with 10V (unless I'm mistaken).
