This octahedron is solid except for the 6 see-through 'wormholes'. It is the only shape I ever made that I have not been able to reproduce in steel magnets. (With colored magnets that are not as strongly magnetic, making this shape might be easier.) Can anyone find a repeatable way to do this? If you find a way, please let me know. The last image shows how the magnets must be organized.
