A mechanism for quickly and precisely positioning one body relative to another body, which relies upon three support points between the two bodies. At a first point a hemispherical surface is received in an opening having the form of a trihedral pyramid. At a second support point a hemispherical surface is received in an opening having the form of a diahedral prism. At the third support point a rigid sphere held in loose confinement engages a flat surface.

A system for removably securing two rigid bodies together at three support points in a fixed and predetermined spatial relationship so that they can be quickly and easily separated and then secured together again in precisely the original relationship, said system comprising: a first body having first and second exposed openings, said first opening being in the form of a trihedral pyramid with its widest dimension at the outward end, and said second opening being in the form of dihedral prism with its widest dimension at the outward end; said dihedral prism of said second opening having a longitudinal axis which extends toward said first opening; said first body also having an exposed supporting surface which lies outside an axis common to said first and second openings; a second body having first and second protruding hemispheres which are so spaced as to be received by said first and second openings, respectively, of said first body; and said second body also having a protrusion adapted to engage said exposed surface of said first body.
