Ender 3 Filament Runout Sensor (adjustable)

thingiverse

I remixed the original part as the outlet hole wasn't aligned with the inlet of the extruder. I've added an L base with a slot to be able to slide the filament sensor and aligne with the extruder. The box is secured in place using at M2.5 screw that hold the bottom part to the base. I broke 2 clips trying to mount the sensor box, so I've added 2 holes, so, in case you just broke them too, you can use 2 M2/M2.5 screws.
