Rush Hour puzzle

Rush Hour aka Traffic Jam aka Tokyo Parking… a multi-puzzle game that goes from very easy to very challenging (the most difficult challenge requires 51 moves).

My modeling aim was to create a very smooth and satisfactory sliding experience, with easy grip and effortless movements.

Instructions: although the blocks could be printed without support, I suggest to print them as they come, laying on one side and with internal support. This way the pieces will slide beautifully. Print a small block in a different color: that would be your car. Have fun, don't stress, is traffic time.
