Solid Chess Pieces | Neodymium Magnetic Balls @ledwatchman

Uploaded April 2012 | Updated September 2026, 1 hour ago

A large sized set of all 6 different chess pieces, made from 5mm neodymium magnetic balls. The design of each one is based on pentagonal layers, and each piece is built solid except I left a one ball hole through the centre of each for ease of construction (the shapes still work fine with this central hole filled in layer by layer). The complete set of 6 uses a total of about 4500 ball magnets. The style of these pieces is intended to be a modernised magnetic ball version of a classic Staunton chess set.

$Cuboctahedron Fractal Sphere Of Spheres - 48 × 48 | Tutorial | 2304 Neodymium Magnetic Balls The small sphere used in this larger sphere of spheres is of 48 magnetic balls, and was designed by KENTAI000, who called it a Cuboctahedron or C48: https://www.youtube.com/watch?v=h4n72c-ndak The larger sphere of spheres is a fractal object with exact self-similarity, in that the structure of the small C48 spheres in the whole shape is exactly the same as the structure of the individual magnetic balls in each single C48 sphere. This gives a total magnet count of 48 × 48 = 2304. I built this fractal sphere as shown from 6 squares of 4 C48s, and 8 triangles of 3 C48s of opposite polarity to the squares of 4. This corresponds to the geometry of a cuboctahedron of 6 square and 8 triangular faces. To build the C48 spheres with opposite polarity, turn each of the 4 completed facets of 12 balls over before assembling the same way, or wind the rings of 9 and 3 in opposite directions from the same line of magnets, or build them the same way but from the opposite end of the same line of magnets. There are a total of fifty facets corresponding to each gap between the spheres, which include triangles of 3 spheres, and squares and rhombuses of 4. I found a GIF online of a polyhedron very close in form to this structure called an expanded cuboctahedron, which I show at the start and end of the video: https://robertlovespi.net/2014/11/12/a-cluster-of-thirteen-rhombic-dodecahedra-and-three-other-related-polyhedra/ In this computer graphic there are 6 blue square faces and 8 green triangular faces of a cuboctahedron, but also 12 red rhombus faces of a rhombic dodecahedron, and 24 extra yellow rectangular faces, which are exact squares in my magnet fractal shape. Each small C48 sphere is also a tiny version of the same unusual geometry.
