Do you like puzzles? Do you like puzzles that do things? Then look no further than the Mechanical Box 3D Puzzle, the puzzle that doubles as a Steampunk card holder.

Once completed, this looks like a prop from a movie in which everyone is wearing long dresses and you can’t throw a rock without hitting some sort of scientist. This really cool puzzle is made completely from plywood and features a series of gears that come together in a small structure that would look great on just about any desk.

It’s not just for looks though, once you’ve assembled this, the box can be used to hold business cards which opens by pushing the swtich. Gimmicky, sure but still pretty cool. There are no tools or glue required to build this. All it takes is time and a little patience. The pieces came on a board and must be pressed out but once that is done, you’re ready to build. If you happen to like a bit of steam in your punk, the Mechanical Box 3D Puzzle is $28.93.
