This design thermoforms very well. There are virtually zero flat spots.

This adds the bolts for tension adjustment. I designed the bolts around M2, M3 and M4 bolts. These are pretty readily available with various head types and lengths. The fabrication guide would have to include a table of the scale of prints and the required size bolts. The bolts are meant to spin freely in the plastic. So those holes will have to be drilled out after printing for many sizes. The end nut should be a locknut. It is the captured nut in the whippletree that moves.
The cover seen in the photos is printed separately and thermoformed, then will slide in the slots.

I wrestled with this design for a while, because I thought it was too exposed, until I added the cover. I like the cover because it makes the design more ascetically pleasing while protecting the small parts. It also allows adding theme elements to the cover itself.
The cover holds on pretty well, but would be the first thing to break off after heavy use. My guess is this is ok.
The sliding parts are very small. They could be difficult to print at sizes smaller than 130% for some printers.
The bolt attachments are small. I want to test how much force it takes to pull these bolts off. I don’t think it is possible to pull them off by over forcing the actuation of the hand. But I plane to test to its limit and see. Breaking these parts off by whacking the back of the wrist against a hard surface is most likely, hence my adding the cover.
I could add more plastic around the bolt attachments without affecting thermoform-ability. This might negate the need for a cover. But, I like hiding the bolts anyway.
I am willing to post this to thingiverse if anyone else would like to test it with me.
