Origami Expanding Polyhedron

[Intermediate] How to fold a truncated octahedron ball that expands and contracts. This model was my attempt at making a polyhedral 3D version of the traditional 8-pointed transforming ninja star. So instead of being one octagon frisbee (2D) this model in its expanded state is 3 intersecting octagons (3D). It uses the same locking and sliding mechanism as the traditional 8-point transforming ninja star. This model is well-guidelined and looks good but getting it to expand and contract smoothly I find very challenging because if you make it too loose it tends to fall apart but if it's to tight then it has trouble sliding apart and together. Perhaps it might work better using printer paper cut square. But as expanding modular polyhedral origami models go, I think this one is pretty awesome (because I haven't actually seen any others!)
