Filament runout sensor

FIlament runout sensor adapter i remixed to use on my direct drive ender 5.
Mounts to 20x20 rail slot.
Insert a piece of bowden tube as a guide and carve out the part where sensor pushes. Notch has to be deep enough and angled for the sensor to unclick. I found it best to first insert the tube and carve while its in place, it may be tight fit for some tubes, if thats the case use allen key to move it around inside the hole to make it bigger.
Print with supports, glue in the pin on the back.
