Update: I believe the mount is making the filament bind up. I will be working on a better path and posting updates. Any suggestions would be appreciated.
I did not like how most of the filament runout sensor mounts for the Ender-3 mounted so close to the extruder. When the sensor activates and the filament retracts it bind up on the runout sensor. So I modified keithcorcoran's great snap on filament guide to hold a filament runout sensor. This should work for many 2020 extrusion machines in addition to the Ender-3. The sensor is held in place by two M3 bolts and nuts. Length will be determined by the thickness of your sensor housing.
