Dodecahedral Bubble Cluster | Tutorial | 4320 Neodymium Magnetic Balls @ledwatchman

Uploaded September 2017 | Updated September 2026, 9 hours ago

The solid 2 layer interlocked sub unit in the video is made from 2 hexagonal/triangular pieces of 12 balls each, so 24 balls for each unit. 15 units go into each of 12 icosidodecahedron hollow 'bubbles', so 180 of these units are required for the full 12 bubble dodecahedron cluster, a total of 4320 magnets. You can easily make a single complete hollow dodecahedron (or icosidodecahedron) with just 20 units (40 triangles/hexagons), or 480 magnets.

$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.
