Servo Z-Probe with micro-switch

UPDATE 12.08.19: I have designed optical probe that is super accurate see. https://www.thingiverse.com/thing:3797852

I got tired BL touch dropping the pin and saw the design 3293821 with servo.

I used the same micro switch but removed the metal lever.

Because my printer has BL touch mount - I made this to fit BL touch fittings.

I also included step file for those who want to modify the height of the fixing - as I have volcano hot end, and it is pretty tall 72 mm

Accuracy of this probe is within 20-25 microns!!

I used servo SpingRC-SM-S2309S, they are not the cheapest, but I had one lying around. can be found in aliexpress
