Simple Puzzle Box

thingiverse

A clever puzzle box, which can be opened by unleashing centrifugal force. To unlock it, follow these steps: It requires adding two nails with precise diameters: - The nail head's maximum diameter should be 4.8mm. - The inside of the nail should not exceed 2.3mm in diameter. The assembly process unfolds as follows: 1 - Cut the nails to a maximum length of 10mm, then smooth out the nail heads to achieve the correct diameter. 2 - Place the first nail in position (start with either side) and secure it firmly. 3 - Apply strong glue to small part 2. 4 - Attach small part 2, covering the inner nail, to complete the initial setup. 5 - Repeat steps 2-4 for the second side. 6 - Ensure that once glued, the nails can move freely within their designated space. 7 - Insert the nails into part 1, then place part 3 (the large decorative piece) on top of the combined parts 1 and 2. 8 - Shake the box vigorously; at this point, the nails will enter part 1, effectively closing the puzzle box. 9 - To open it, simply twist or rotate the entire box on a flat surface to release the centrifugal force. This will push the nails into place, allowing you to remove part 3 and access its contents. Enjoy your new puzzle box!
