3x3 Slide Puzzle

thingiverse

This is a re-creation of the classic 3x3 slide puzzle, designed for commercial use with precision tolerances at 1mm. It's commonly printed at a scaled-down version of 70%. You are free to sell these puzzles and I typically charge $4 or $5 each when printing at 70% scale. In commercial settings, I kindly request a 10% commission on the sale price, although I have no mechanism in place to enforce this request. However, if you're selling casually to friends or giving them away to children, no kickback is required. If you get stuck, try this hint: Sometimes, you need to undo the correct moves to make room for new pieces in their proper spots, much like a Rubik's cube.
