Underbed piezo mount for Kossel Delta Z probe - Parametric

Underbed piezo sensor Z probe mount for Kossel Delta. Based on Moriquendi piezo system (https://reprap.org/wiki/Underbed_Piezo-electric_sensors), but placed the mount along the horizontal beam and moved piezo to the bottom side of the mount away from the heat area.

I used piezo discs 31 mm in diameter (crystal diameter is about 20 mm). Mount central hole is for M3 brass insert nut. Used M3 x 20 mm round head screws with fiberglass laminate washers f
