Big Ball

This CAD model was designed by Oskar van Deventer, copyright (c), 21 May 2026

Big Ball is an assembly puzzle with 60x14=840 sticks, 1.7 kilogram, and 70 centimeter diameter. It is a tribute to Derek Bosch' Icosahedron Frequency-3 Sphere puzzle ( https://www.printables.com/model/1692526-icosahedron-frequency-3-sphere-puzzle/collections ). The sphere is held together by tension. Assembly is time-consuming but easy, as all notches are marked with a letter. "A goes into A", "B goes into B", etcetera.
