Klotski - Sliding Puzzle

Ready for a real challenge? This Sliding Puzzle is a tough and satisfying brain teaser where the goal is to slide a 2x2 block out through a slot — but there’s a catch: you only have two 1x1 gaps to move your pieces around! The puzzle includes a mix of 1x1 and 1x2 blocks, arranged in a way that will test your spatial reasoning and problem-solving skills. Designed to print fast and clean, the case fits all blocks snugly and features an open top and exit slot for the goal block. No supports or AMS required!

The model prints in separate parts: a base box, one 2x2 goal block, 9x 1x2 blocks, and 12x 1x1 blocks. Customize the colors for visual appeal — I recommend red for the goal block for contrast and speed, with the others in green or white.

Challenge your friends or use it as a brain-boosting desk toy. Once solved, mix the pieces and try again — there’s more than one way to win!

⚙️ Prints well on most 3D printers. No glue or assembly needed.
