Infinity Cube with adjustable tolerances and magnet holes

I wanted a fidget toy and wasn't satisfied with the sloppiness of the existing models, so I recreated one in OpenSCAD and added optional magnet holes. The STLs are examples for 3x4mm magnets or without holes, I've printed the shown examples in: QIDI Tech ABS-GF25 (black) mechanically perfect but not suitable for toys due to possible skin irritation unless you seal it eSUN PLA+ (white) feels nice but does not have the high rigidity of PLA AMOLEN Silk PLA (RGB) looks and feels great but does not bridge well
