Piezo Bed Leveling Sensor

thingiverse

Simple way to get a reliable Z-Probe without disrupting the extruder's performance. It works flawlessly with my custom extended Rostock design. In addition to printed parts, three Piezo sensors, three 1M resistors, and an Arduino Nano (for simplified implementation) are necessary. To add some flexibility, the bed is secured by a spring and M3 screw.
