First of all - this puzzle can be solved! If you've already solved it, please don't spoil it for others

You will need six magnets with dimensions of 4mm x 1mm. Use glue to fix them in place.
Start from one side - place all the magnets on the same pole
Then place a free magnet on this side. It will align with the same polarity. Then just press down on the other side
I've added a text editor to customize it - now you can easily make changes.
Every part has a name in the design - just change the side_text attribute, as shown in the screenshot.
To close the puzzle, the best option is to place two pieces on each side and close them at the same time - you'll get a beautiful box.
