I saw this Puzzle on the YouTube Channel from Mr. Puzzle.
I was amazed how difficult a three-Piece Puzzle can be. So i decided to design and print it.
I Used 4x2mm Magnets
You can find the Solution here: https://youtu.be/4zQmkyH0Mr0
Add the Magnets in a Way, that you can solve the Puzzle. (Mind the polarity)
The other ones can be in a random polarity.
The author marked this model as their own original creation.
