Original design by Matt Shepit. The version fro, Thang Nguyen is built very exactly and turns nicely. I found for me personally the mechanism (design, not the way it was built) becomes tiring after a while, because you have to check the sides all around the puzzle, if they are aligned properly for the next move. But that is the nature of this item.
Size: edge length 6.5cm; circle diameter 4.3cm
