Summary

This is a magnetic version of "Coffin's Half Hour Cube".

Within each cube of each part is one 5mm ball magnet. Each ball magnet can rotate freely. In this way, all puzzle parts can snap together in each direction.

This allows the composite cube hold together.

To place the magnets within the parts, the Print has to be paused before the inner holes will closed.
