I worked for some time with the notion of doing a biomimetic approach to constructing a telepresence hand by using mixed plastics extrusions. It turned out that the finger joints were made with what amounted to a fluid filled bag harnessed in with ligaments. I could do the ligaments but had no hope of printing a fluid filled bag at the scale required by a human-sized hand.
From there I've designed pinned hinge joints. It was a real challenge understanding how to print a 0.84 mm hole accurately for the pin. I finally came up with a workable approach last weekend.
At this point I know how to do the joints and now face the problem of securing the latex band that contracts the finger.
It is nice having a little time to work on the project after the loss of last Fall and much of the winter to the demands of my day job.
