Simple Voron filament sensor that secures the Bowden tube

I can't upload this as a Voron usermod, because I can't meet all the requirements with the CAD file format, printing without supports, the editing of a Readme table, the creating of a subfolder, etc. etc.

Nevertheless I hope you will enjoy this and find it useful. I looked at dozens of filament sensors, but none fitted my requirement of having a Bowden coupler threaded into the top, the filament entering underneath (this is where I thread the filament into my machine), the standard microswitch concealed behind, and being fastened to the left side of the Voron 2.4's frame (should work with the Trident too).

This can either be used with the standard filament spoolholder (attached to the frame below this), or a filament drying box as I use.

This is printed with supports under the end that fits onto the frame.

Use 1x 20mm M3 screw, 1x M3 T-nut (the twist-in type), 2x M2 self-tapping screws, 2x M3 nuts or similar spacers as required for the self-tapping screws, 1x microswitch with lever.

My printer.cfg contains the following:

[filament_switch_sensor Filament]

pause_on_runout: TRUE

runout_gcode: M600

event_delay: 300 #Five minutes of printing after sensor is triggered

pause_delay: 0.5

switch_pin: PG11

Note that PG11 might not be the right pin for your board, I'm using the Octopus board that came with a Formbot kit. Search for your board name and the word 'pinout' to find the pin names.
