custom clicky probe for V slot mounting (and sapphire sp-5 with enclosure)

inspired by the original clicky probe mounts and parts. I just didn't like how they interfaced and how loose the probe was held in the arm.

This mount uses slightly larger (15kg / DT996) servos as I tried it with smaller (MG90S) ones and they struggled and started to oscillate.

Mount gets attached with two m3 screws and t-nuts. Servo arm is pushed on the original lever arm and screwed in place. interface print has place for a small magnetic screw and the arm has a cavity for a 6x3mm magnet.
