Huzzle Cast Rattle - Grandmaster difficulty

Separate the 4 parts and put them back together!

Four similarly shaped pieces are loosely fitted together to form this puzzle. All the pieces fit together easily, making it seem as if they could be easily taken apart. However, you'll soon find yourself at a loss, as the puzzle offers no clue as to how to solve it. The trick is not to overthink it, but to calm your mind while you tackle the challenge. American Bram Cohen designed this puzzle.

The topic is relaxed.
