Rear right foot for voron v0.2 with filament sensor

For the 2 other people who don't want to to reprint the entire skirt for the v0.2r1 release to get the filament sensor.

I didn't need the extra 2 mm in the skirt, But I've been looking for a filament sensor. Uses the exact same hardware, its the exact same filament sensor with the same tolerances in a 2mm shorter assembly.
