25 Cent Puzzle v2

thingiverse

This is a modified version of https://www.thingiverse.com/thing:3839352. A simple yet clever puzzle box inspired by Jean-Claude Constantin's 20 Cent Box can be created with a few modifications. The original design was first introduced through a Mr Puzzle video on YouTube, which provides a spoiler alert at the end (https://www.youtube.com/watch?v=aVjmwW8QCNk). After printing, small 6mm diameter and 1.5mm thick magnets should be glued into the holes to ensure proper functionality. The front plate with slots must move freely within its grooves while the back plate remains firm. A standard US quarter or any coin of approximately 25mm in diameter and 1.5mm in thickness is required. Significant changes have been made to enhance the puzzle box's complexity and challenge: 1. The size and thickness of the box have been increased. 2. Magnets are now hidden from view, requiring a different approach to solve the puzzle. 3. The back plate is fully supported, preventing it from being pressed open accidentally. 4. Additional false holes have been added to mislead the solver. 5. A chamber in the bottom holds 10 pennies, increasing the box's weight and providing a satisfying heft.
