Ginkgo Puzzle, 3D printed

It's a simple Combination Puzzle, with ginkgo-leaf-shaped pieces that turn in place to free or bind their neighbors. One object of the puzzle is to get all of the pieces pointing in the same direction, then get them all pointing in the opposite direction.

I've been drawing doodles of this puzzle for years, and hoped that it would turn out to be as interesting as the Fifteen Puzzle (sliding square puzzle). It turns out it's almost trivial: to move a piece you need to move a triangle of pieces that start at the board's edge, and has that piece as its apex.
