I think I get what your saying but even a close pin while hardly noticeable, changes length for phantom tip to tip if configured with the pivot and square distance between the tips. the radius is the same sure. The length measured between open and closed changes on a symmetric orientation down the origin lengthwise. I think it might be possible without 90º L sections but +15º and a pre unit at -15º so u still need an extra step. But idk. Need to cad it out
