Solid State Bouncy Ball

thingiverse

A C60-shaped structure, featuring pentagonal and hexagonal plates, was designed by Pat in 2001. This design connects the plates to the central core with coil springs. Users are invited to download and assemble it. However, there's a flaw - insufficient filleting at the "coil-to-plate core junction" and "plate junctions" can compromise its resilience against cyclic deformations. This issue doesn't affect nylon-made structures, though. For optimal performance, generously apply fillets to stress points, especially at acute junctions. Springs should be modeled in an overextended position, as they tend to deform to a stable state after initial use. The structure exhibits bouncy behavior similar to a rubber ball. Pat requests photos of completed projects and wishes everyone an enjoyable building experience. For optimal results, use materials like nylon processed through SLS systems, where support structures dissolve away.
