Auto-level trigger for induction bed sensor

This is an updated version of my "Poor Man's BLTouch" induction auto-trigger. It works for any printer that leaves enough of the induction sensor barrel exposed to attach this trigger part. USE AT YOUR OWN RISK.

This trigger relieves the user from having to attach pieces of metal to a non-metallic bed, exposing the full bed surface for printing after performing a fully automatic leveling calibration. After the measurements, just remove the trigger and put it away until your next bed leveling calibration is needed.

*IMPORTANT: If you are using the fully automated auto-leveling behavior in your printer firmware, you MUST* remember to attach this trigger to the carriage before starting the bed level measurements! Failure to do so may result in a forcible nozzle crash, and related mechanical/electrical damage.

The part works for me when printed in TPU. The part will become slightly warped if used for extended duration over a heated bed, but should still have plenty of flex in
