End of filament sensor Bowden Edition (run-out sensor)

thingiverse

Remix of bookmake's End of filament sensor (switch) https://www.thingiverse.com/thing:1134134 I found the mount to be very well designed. However, while it works great with most setups, it would not work so great for my setup that has bowden tubes from filament dry box, into the case, through the extruder, and to the hot end. I also added a view window that doubles as a directional arrow. This just needs 2 M3 nuts and 2 M3 screws and splice into a bowden tube. The rest is pretty easy to setup in the firmware. Here is a helpful guide if needed: https://nutz95.wordpress.com/2017/03/10/filament-change-module-runout-sensor-for-reprap-3d-printers/
