Icebox extension

Plenty of nice cool beer in the icebox.
But, as soon as you take it out, it starts warming up.
So, think out of the (ice)box.
We need an icebox extension. A 3D printed icebox extension!
It actively cools a bottle, tin or glass of beer outside the box.
A small Peltier element (4x4 cm) is used, which is a low cost heat pump. It transports heat from one side to the other. As soon as electric current flows through the Peltier element, one heat sink heats up, while the other cools down.
