My problem is explained more in my attachment, but briefly, I require some form of equation or graph to calculate where the pivot points within a seven point hinge system need to be in order for the rotating edge to rotate around a origin.

The question is in regard to the hinge system.
I require the hinge, when expanded, to rotate around the origin with 0 tolerance.
THE HINGE
What I know
Through pure trial and error, involving no mathematical formulas or graphs, I have
narrowed down where the pivot points, approximately need to be placed so it rotates
around the origin.
I did this by lengthening and shortening distances and angles between points, until I
narrowed the solution down to be within 2mm tolerance.
As can be seen in the picture below, the plate that will be used to bend the material
moves up/out/in/and down while rotating around the origin. I require this plate to have no
tolerance, i.e. not move away from the origin at all. Therefore I believe there must be
some sort of graphs or equations that will dictate exact positions the pivot points within
the hinge need to be.
