Route the cable through the microscope mount?

[mmalecki]

We could route the camera ribbon cable through the microscope mount. This would shorten the cable, but would require a A-A cable (as opposed to RPi camera's default, A-B), and moving the Pi to the front of the Z pillar.

If we want to avoid RPi encroaching on work area, we would need to use a 2040 (instead of 2020) for the base extrusion.
