Additions for Articulating Raspberry Pi Camera Mount

(1) I wanted longer arms for the articulating mount, so I made them based on the originals.

(2) I took the gBlock (end piece filler) and attached a ribbon chain segment to it so I can protect the camera ribbon. (I haven't installed it yet, since it requires removing the ribbon from either the camera or the pi to thread it through the chain. I'll be doing that shortly, when I stop printing things.)
