For such a seemingly simple puzzle, this one caused me a lot of problems to manufacture. There were originally supposed to be 40 made; only 14 turned out due to a couple of bad assumptions I made in the shop. Even so the price is somewhat discounted as the cuts are not as clean as I would have liked...due to the angles involved, I actually believe you have to have a saw that will tilt both right and left to make the cuts perfect. Errors are not very noticable once the puzzle is assembled, thankfully. Signed and dated.
