A nice packing puzzle designed by Frederic Boucher. This puzzle receives very positive reviews by puzzle fans, and has been remade several times (though only a few hundred were hand crafted each time) The goal is to fit all Tetris pieces into the box.

Below is the official link. It costs more than 3000 bucks. Even if you have the money, it is already sold-out. X(

Modeling using puzzlecad, an open source OpenSCAD library. Source code is also uploaded. Download puzzlecad library, put the *.scad file into the folder and open it. Then you can easily change size, inset, bevel, etc. Remove the * before the model (one line a time, add * back for the next), and press F6 to render, then export the *.stl file.

Some extra notes:
As a packing puzzle, it plays more like a turning interlocking cube. Took me nearly 1 hour to solve. Solving the puzzle takes dozens of moves in total, and there are some tricky ones. But it is more about logic instead of trial and error. You guess the final state of all pieces based on holes (it’s easier to refer to the link above), then you infer the state before it, till the initial state. Based on your inference, put the first piece roughly in place, then second, third and forth, finally the long stick. Breaking the puzzle down into a sequence of small puzzles makes it much easier.
