MK4/S x-axis mount for articulated arm

Added GoPro-like connector derived from @PointNemo's MK4/S-x-axis-motor-cover to work as an ESP32 camera mount using @MichalFanta's articulated arm system. As always, I appreciate these efforts as they helped make these changes easy.

I previously had the esp32 camera mounted to the bed extrusion but wanted the captured images to follow the print head vs. from a static position. This mount works perfectly.

Printed using Prusament Orange PETG

• layer height: 0.2 mm
• infill: 15 %
• perimeters: 3
• seam position: random
• supports: none (i didn't use any but your mileage may vary)
   

Update: I mistakenly uploaded an interim model; v7 is the correct one. Apologies for this public offense, but knowing myself, it won't be the last. ;)
