It's not much, but it should give you a slightly better idea on how everything fits together. It seems that I've sketched the mirrored version of what I intended.

Also note that the bottom of the steel tubes are slightly closer together than the top, This is to give the ball-chains more space. The angle is only 2 degrees, which isn't significant enough to have 2 slightly different bending jigs. It's possible that I increase the angle should I need more space, but right now I've kept a 1.2mm gap for the walls of the printed part that holds these in place. The tubes also act as reinforcement for this printed holder.
