At last!
I'm finished with the new stepper phone stand upgrade 3D-printing of parts and assambly

The upgrade consists of several new features.

+ Housing that holds Stepper motor and bearing

+ Housing that holds raspberry Pi and all electronics.

+ Hall sensor for homing B-axis

+ New slim construction of the telephone stand that is much slimmer and lower to make movement of C-axis better.

Stuff that still has to be done:

HMI for operating functions of the FaceFollowPhoneCamTurret

Remote control construction and soldering of electronics

The fun stuff:

Programming!
