G4.7 Mini Kinetic Wall — Full System at 29.375% / A3

A complete miniaturized kinetic wall system scaled to 29.375% (4.7/16) of the original 900×1200 mm design, fitting within an A3 envelope (297×420 mm). This full-system reference preserves all original mechanism families—hand-crank elevator, teacup, paddle wheel, Plinko field, switchback, loop, alternator, and cascades—with steel-ball magnetic supports and glued mounting shoes. The system demonstrates scaled track routing, depth transitions, and modular cassette interfaces, though clearances, reset forces, bearing loads, and magnetic attraction require print-specific qualification before functional use.
