Quick adjust mount for inductive sensor LJ12A3-4-Z/BX using the second extruder mount point on the MM3. Uses a corner bracket spring from ultibots for sensor retraction.

Shown mounted with sensor going through second extruder hole, but bracket can be flipped around to make the sensor forward facing.

For initial setup and course adjustment, push down on the sensor and tighten the top nut so there is some tension on the spring and the end of the sensor is near the activation point when the sensor is not depressed,

For fine adjustment, push down on the sensor and tighten/loosen the bottom nut to increase/decrease tension on the spring and bring the sensor closer to the bed.

Print on its side and no supports are necessary.
