A compact z-probe designed around an ultra subminiature switch with friction fit and separate contact point
This probe was designed around an ultra subminiature switch such as the OMRON J-size D2F series. The goals of this probe design were to utilize a very small switch for the probe, use little to no additional hardware, and utilize a floating pin as a contact point rather than the switch itself.
The scad is parameterized so you can adjust values for your own servo arm, switch, and floating pin. The double dovetail should provide a good friction fit with minimal filing or sanding.
