Sudoku Puzzle Box

thingiverse

This fully 3D printable box remains locked until the Sudoku puzzle displayed on its top is solved. The puzzle is shown using knobs pointing to numbers on the box lid. Some knobs are fixed (these are the filled-in numbers on the puzzle) and some can be freely rotated. As they rotate, a detent mechanism gives tactile feedback and keeps the pins in place. Once solved, a button on the front of the box is pressed, and the top becomes free to lift off the box. The puzzle is customizable by rearranging different combinations of pins. Parts: * Box.stl - This is the base of the box. * Pins-moving.stl - These are all of the rotating pins needed to make any Sudoku puzzle. Included are 81 pins, 9 corresponding to each number. The number each pin corresponds to is printed on its side. Also included are cylindrical supports up the side of the pin. This improves stability, as the pins are tall and have a narrow base. - Pins-fixed.stl - This is similar to pins-moving.stl, but contains pins that are fixed in position and cannot move. These are used for the "filled in" numbers of the puzzle. * Slideplate.stl - Part of the locking mechanism. The front part of this protrudes as the button (so print it in the desired color for the button). * Clips.stl - Internal to the box, these hold the mechanism in place against the lid. * Baseplate.stl - The base of the internal mechanisms. It also contains the detent prongs. I recommend printing this in PETG to allow for some flex. * Lid.stl - This is the top part of the box. On its face are printed circles of numbers, so ensure your bed is level and Z height is set correctly. * Knobs.stl - These knobs press on top of the pins to make them easier to grip. Print 2 sets of these, one in the color for fixed pins, and one in the color for moving pins.
