Ender 2 Pro / Ender 3 (Cheap) Runout Sensor Mount

This is a mount for an Ender 2 Pro or Ender 3 to hold a cheap runout sensor from AliExpress. ($1.50)

My runout sensor seems to be a bit different that the other ones, so the other designs did not work for me.

I designed it for the Ender 2 Pro, but I believe it should work for Ender 3 also if you have your filament spool attached on the side.

Use 20mm M3 bolts to hold the sensor in place.
