Spheregrity 2

This CAD model was designed by Oskar van Deventer, copyright (c), 30 May 2026

Spheregrity 2 is a joke member of the Spheregrity family. In the quest to ever lower number of pieces, two is the minimum if the requirement is that each piece need to lock with another piece. The notches are at the vertices of a tetrahedron. Its shape of the pieces was determined by a spline on a sphere.
