Origami box with Lucky Star molecule. The molecule can be tessellated and is based on hexagonal 8×8×8 grid.
I called it this way because I was happy about this design which I find quite elegant. Even though I have seen some similar ideas (e.g. by Alessandro Beber and Peter Keller), I wasn’t able find proof of anyone creating exactly the same design before, so if it really is new, I will feel lucky to have found it. If I do learn of someone folding it before, I will still feel lucky to have reinvented it.
Update: I learned that the molecule is structurally almost the same as Day and Night Tessellation by Haligami, the only difference being how the rays of the star are locked. Thanks to Tomek Czunko for pointing this out.
In order to make teaching at conventions easier, I also designed a simplified version of this box.
