Filament Runout Sensor for Voron side entry exhaust.

I designed this to fit my Voron 2.4 side entry exhaust housing remix, which is listed separately.  

It houses a common KW12-3 roller type microswitch,  and replaces the tube guide/funnel on my side entry exhaust housing remix.  It requires one m3 heat set insert, one m3x8mm socket head cap screw, one KW12-3 microswitch and one jst 2.54 connector set.   

I printed mine in ABS, and used a couple drops of superglue to secure the microswitch and electrical connector.  Be careful installing the heat set insert, as the thin wall in that spot can distort easily.  Gently push strait down.

When loading filament,  too much curvature to the end of the filament makes it harder to get into the sensor.  Straiten the end a little and it goes in very easily.
