The Star of David puzzle is a 24 sided solid with six axes of rotation, and each axis having two rotational layers. The six tips of the puzzle can turn in 90 degree increments, while the next layer below the tips can turn in 180 degree increments. The Star of David is essentially a higher order version of my Ice-9 and Rhombic18 puzzles.
The Star of David puzzle comes as a DIY kit of parts, and you will need to supply your own stickers. The templates for the stickers are available in the instructions forum
I recommend that you purchase the puzzle in "Black Strong & Flexible". It costs a bit more than the white material, but it's worth it since the finished puzzle will look and work better. All of the parts snap together, so no additional screws, springs, or other hardware are required.
