This is one of Stewart Coffin's most difficult puzzles in the genre of "shape shifters" which have multiple symmetrical configurations possible. All of the photos of this bocote wood version are showing it in the namesake Star-of-David configuration, however others are possible too. You can see photos of those other configurations here.

Even once you know what shape you are trying to make, it is still hard to get the pieces assembled because for most of the solutions the axis of disassembly does not coincide with the axis of symmetry. Truly devious, yet extremely satisfying when you get it right and suddenly order emerges out of chaos!
