Mechanical Filament Runout Sensor for Prusa i3 MK2s

I wanted the runout sensor as close to the extruder as possible and since im using an enclosure it never was an option to have it outside the enclosure.

The printed part is attached using the zip ties spare from assembly. A short to attach it to the Pulley Idle and a long to close the "box" and keep the sensor in place.

This is built for use with the black mechanical endstop
