>>5357571One thing that was happening back in the Polynian threads was we had a guy making custom high heels for the models. He had to go through a few programs, but he used the measurements for the commonly purchasable Hobbybase globe joints (which Polynians use) to make CAD models for high heels which he then prototyped, and is now selling on Shapeways for $10 a pair.
Making joints via 3D printing usually isn't as viable as simply making parts. Pre-built hobby supplies like the globe joints could help for those who wish to make figures of their own, and it was something that was discussed in the threads too.
We also had a guy a while back posting robots he sold on Etsy made via 3D printing. They had screws to hold them together which doubled as joints, and the robots had pretty good articulation to boot.
