A simple puzzle box, which can be opened by using centrifugal force. Prerequisites: It is needed to add 2 nails with the diameters indicated in the picture: nails head max diameter: 4.8mm inside nails max diameter: 2.3mm Mount steps: 1 - Cut the nails to get a max length of 10mm. Next, sand the nail heads until getting the correct diameter. 2 - Put the first nail in place (left side or right side, start with the one you prefer) 3 - Put some strong glue on the little part 2. 4 - Put the little part on top (covering the nail inside) 5 - Repeat the steps 2,3 and 4 for the next side. 6 - Ensure, once glued, the nails can move freely. 7 - Push the nails inside part 1 then put the part 3 (the big ornament part) on top of the assembled part 1 and 2. 8 - Shake all and at this step, the nails will enter in the part 1 so the puzzle box is now closed. 9 - To open the box, twist/rotate the entire box on a table for instance to open it. The centrifugal force will push the nails inside the assembled part 1 and 2 and then you will be able to get out the part 3. Done. Enjoy :-)
