yellow part is a rapid prototype part, probably nylon from a SLS- selective laser sintering process. Awesome stuff, and I found a website a while back from a company that will make it and send you the part on the cheap.

as far as the slop in the arm, that does make sense about twisting it, but wouldn’t it cause binding to have the joint maxed out?

also curious how much those tube clamps weigh.
