Stellated Icosahedron Of R60 Mini Spheres | 5520 Neodymium Magnetic Balls @ledwatchman

Uploaded February 2013 | Updated September 2026, 3 hours ago

Composed of 92 of what I call R60 spheres, (R stands for Rhombicosidodecahedron) of 60 neodymium magnetic balls each, which also function here as little icosahedrons. All bonds in this shape are across triangular faces of three magnets. To make these bonds strong I deformed the R60 spheres at each connection so they kind of slightly intersect. Thanks to Kevan of channel 88625652 for the precise geometric model of 92 interconnected icosahedrons this shape is based on, see his computer model here:

Stellated Icosahedron Of R60 Mini Spheres | 5520 Neodymium Magnetic Balls

$Rhombic Fractal Hemisphere Mega Cluster | Part Tutorial | 7632 Neodymium Magnetic Balls This large hollow cluster shape is built from 5mm neodymium ball magnets and uses 2 fundamental units: a solid interlocked pentagonal one of 21 balls (in gold) and a solid interlocked square one of 17 balls. 5 of the square units fit around the pentagonal unit to make each mini hemisphere subunit of 106 balls, 6 of which interconnected form each of 12 larger hemispheres. These 12 hemispheres interconnected in turn form a mega cluster sphere. A total of 6 × 12 = 72 pentagonal units, and 5 × 6 × 12 = 360 square units. A total magnet count of the 72 mini hemisphere mega cluster of: 17 × 5 + 21 = 106, 106 × 6 × 12 = 7632 magnetic balls. 2 large hemispheres of 6 subunits each can be easily connected as shown to make a smaller sphere of 12 × 106 = 1272 balls. The full 72 mini hemisphere cluster is a lot trickier to build but once completed it is very strong, because the units used to make it are solid (in compact form). If you look closely at this structure you can find fractal quasi self-similarity (partial but not exactly identical) among 3 levels of scale that resemble the geometry of a rhombic triacontahedron (a 30 diamond sided polyhedron). There are also symmetrical gaps formed among the units that make the whole structure look weirder.
