Filament Run Out Sensor

Filament Run Out Sensor
====================
My version of a filament run out sensor using a V-156-1C25 roller switch. I designed this to either free hang below your extruder or mounted vertically or horizontally to an aluminum extrusion with an M4 T-nut/M4 machine screw.

## Updates
### 4/28/2020
* Prints look good, everything works as expected
* Updated the M3 holes on the top cover so they are a bit bigger so the M3 screw won't thread through them
* Added photos of the print
