Nervous System 2-in-1 Challenge Puzzle
A few years ago I made two Amoeba puzzles by laser-cutting maker Nervous System, and was blown away by the difficulty. While the puzzles only had about 70 pieces, they took more than 2 hours each - and I was trying my hardest - putting them near the top difficulty of any puzzles I've done.
Here is the next level. The challenge puzzle consists of 342 pieces, with no printed image. You can also not tell which side is up or down. The only hint you have is the grain of the wood, and at least in my copy the wood has little markings. The purple pieces on the right consist of a 74-piece Amoeba puzzle, and they are stained on both back and front, making it impossible to tell which way is "up." (The other Amoeba puzzles had printed features on one side only.)
Part 1 of the challenge is making the Amoeba puzzle. Part 2 is making a larger puzzle, including all 342 pieces, in which the purple pieces all fit, but never link up with each other. The shape is rectangular but with no straight edge.
