Flexible filament runout sensor

thingiverse

Remix of 3djpco's filament runout senso which uses a creality limit switch. I removed the original mounting tabs and added pivots to allow the sensor to rotate about the Y and Z axes so that the filament does not bind when the printhead travels to high values of X and Z. I used M3 screws loosely threaded into the printed parts to act as the hinges and pivot, and M4 screws and T nuts to mount it to the top of the frame.
