Octahedron Black Widow Spider

I'll finish the week with one final pattern that shows that Octahedron patterns don't have to be so complicated-looking.

Each face shows an hourglass, resembling the markings on a black window spider. It's a natural shape for this kind of puzzle, and it can probably be done a few different ways. As shown in the end-view at right, each "hourglass" pairs a mobile edge piece with a non-mobile center piece without involving any corner pieces.
