Filament runout sensor

A simple filament runout sensor. Require a switch with a wheel like this: https://www.amazon.it/GTIWUNG-Pezzi-Interruttore-Levetta-Finecorsa/dp/B08357RZ7N

No screws required, should be a tight fit with the switch. A PTFE tube can be hard fitted in the in/out. I used a capricorn PTFE tube, wich diameter is 4mm.
