Replacement knob for microwave

I somehow lost the knob for selecting the power of my microwave. It took several iterations but I finally made a new one. It is not winning any prices for beauty, but it works.

It is made out of two parts: The thing that acually plugs into the microwave and a round knob. That way I can replace them idependently when one breaks.
