Filament Runout Sensor Mount 2020 Extrusion

From the .SCAD file:

// A very simple 2020 mount for the common filament runout sensor
//   -- designed to mount to top half of rail with 25mm M3 and T-Nuts
//   -- has a stout spout for reverse boden tube friction fit
//   -- clears the common Voron panels with foam
//   -- prints with no supports, so...
//          please excuse the crude aesthetic!
 

I printed in my Voron accent colour using ABS but anything will work (outside the enclosure anyway) and the infill can be reduced.

Also, I see some complaints that these sensors have a bad choice of colour code on the wires, but mine seem to have been wired correctly: Red is 5V, Black is GND, and White is the signal.
