An articulated neck joint that fits between Sophie's shoulders and the base of her head. It is double jointed and has 360 degree rotation.
(((PLEASE NOTE: if you are going to use this joint with Sophie's body, then don't bother printing out the neck that comes with Sophie's v2 head, because that is just a hollow case with no articulation.)))
This neck joint is designed to use 2 x steel M8 40mm long bolts and 2 x M8 nuts.
The ball bearing in the base of the neck uses 6mm plastic BB gun pellets.
The joint looks a bit thin on it's own so I used some fabric from an old white pillowcase and some white ribbon to bulk it up and disguise it a bit. The joint will move just fine as long as you don't bind it too tightly.
UPDATED 22-07-2019 Modified the joint so that the M8 bolt heads are recessed. This makes it much easier to tighten and loosen using a socket wrench.
It is best to print the top ball bearing race (the base of the revolute joint which sits inside the neck) with the joint facing down towards your 3D printer's build-plate. Although this uses more support material it's necessary, because if you print with the ball bearing race flat to the build plate, then you will get support material inside it and your ball-bearings won't run smoothly. You can attempt to print this part without any support, but I doubt that the hole in the joint will form properly because there is an overhang.
