Raspbery Pi camera ball socket w/ usb & ethernet plugs

2 ball socket remixes: to use a USB socket and more robust Ethernet version with clip

Remixed from 3 great designs.
Ball socket 1mm taller to improve stability from ball slipping out.
Ball diameters on the x & y also increase by 1mm to increase tight interference.

Modified the USB plug to remove lower edge support, allowing the actual USB plug to lay flat on the bed and get a clean model without supports needed.

Used ethernet plug with clip to lock in place.
