Full-sized Articulating Spine

I added markings on each piece to keep things more organized for assembly. A couple of the first ones I did were a little small but they should all still be readable. I also added a small hole through each piece so fishing line or thin wire could be fed through to ensure everything stayed connected. I printed the original version with ball joints vertical and had issues with strength, printing the ball/socket horizontal to the bed was much stronger but also added challenges.
