This is a knob for the CO2 pressure regulators which are common in Europe. These regulators are often used in homebrew setups where you often have to change the pressure setting on the regulator itself. The original hex-shaped knob is not very handy for changing that quickly.

I know there are other such knobs on Thingyverse
