Raspberry Pi Camera Mount Accessories

I really like sonnylowe's [remix](https://www.thingiverse.com/thing:1436055) of Dvogonen's [raspberry pi camera case](https://www.thingiverse.com/thing:536828). The "mid-hinge" arm that sonnylowe added is useful, but I wanted to be able to articulate the arm in 3 axes rather than in just 2, so I modified the mid-hinge arm segment to have a right twist and a left twist. Alternating the left and right twist arm segments provides 3 axis positioning options. Other combinations of the 3 "mid-hinge" arm segments work as well.

I also needed some cable management for the long Raspberry Pi Camera cable that I purchased. I created a ribbon loop that attaches to the end of any of the 3 mid-hinge arm segments, and I created a "clip_ring" that snaps on the middle of the mid-hinge arm segments. See the pictures.

mid_hinge_left_twist, mid_hinge_right_twist, and ribbon_loop all need support when printing. If anyone is interested I could modify the ribbon_loop so that the loop rests on the
