Spring loaded Bed Leveler calibrator for Replicator or Flashforge

This is a remix of hyla's "The Calibrator". Added internal spring capability/rubber band so you do not need an external rubber band, and changed the magnet mounting area for greater options on magnet types. I printed with support and filed the ruler opening, may work without support. Follow "The Calibrator" instructions.
