Repulsive Soma

This CAD model was designed by Oskar van Deventer, copyright (c) Samuel Farinas & Oskar van Deventer, 2 January 2023

Repulsive Soma was developed by Samuel Farinas after a design challenge (and several failed design attempts) by Oskar. The design challenge was to develop a Soma Cube that has a unique solution and as few as possible repelling magnets at its faces. Samuel found a design with only 24 magnets (Repulsive Soma), which he later improved to 20 magnets (Not SO MAgnetic). When the puzzles is assembled into a cube incorrectly, then the magnets push pieces out of place. Surprisingly, the magnets pull the whole cube together in its solved state. So the magnetic cage is only for transport purposes.

The puzzle uses twenty-four 5x5x5 millimeter magnet cubes: https://www.supermagnete.de/eng/cube-magnets-neodymium/cube-magnet-5mm_W-05-N
