Mixed Filament runout and guide - Anet A8

Very simple filament runout switch (1.75mm filament, mechanical endstop with roller arm) with filament guide. I mixed two other designs ( sb43201 and jrwells) ; https://www.thingiverse.com/thing:2577717 and https://www.thingiverse.com/thing:1795148.

I wanted a position close enough to the extruder, firmly fixed and no screws for the mechanical endstop. The chosen solution is to use the initial place of my filament guide (https://www.thingiverse.com/thing:1795148).
