Sound Box

This CAD model was designed by Oskar van Deventer, copyright (c), 18 November 2025.

Sound Box is a tribute to the work of Kagen Sound (https://kagensound.com/, previously Kagen Scheafer). Kagen has used this stripy pattern in several of his wooden puzzle masterpieces. This puzzle is a cylindrical variation. The goal of the puzzle is to turn the 15 disks, and to make the seven beautiful "sound patterns". One of them opens the box, but which one?

Once opened, one can remove the treasure from the cylindrical core. One can then disassemble the puzzle, disk by disk. Seven of the disks have an M3-cheese-head screws that connects them to a disk seven layers lower. These screws can bump into each other and limit rotation. This is what makes the puzzle non-trivial to solve.

The disks are aligned with 154 2x2x2-mm cylinder magnets: https://www.supermagnete.nl/eng/disc-magnets-neodymium/disc-magnet-2mm-2mm_S-02-02-N The puzzle also works without magnets, but then it takes additional effort to keep the disks aligned.
