Nickel Puzzle Box

thingiverse

This is a compact puzzle box designed to hold a nickel. Three distinct models have been uploaded, each necessitating the use of a different sized small ball. The goal is to select the model size that matches the diameter of your available small plastic ball or round bead. To witness the full solution and understand how the box operates, you can view the included video in the photos or click on this link: https://youtu.be/UGnz6Ecnk24. The models are engineered to utilize a 10-24 screw and nut to assemble the puzzle. A 1.25 inch long screw is used initially, then trimmed to size after determining the thickness of the puzzle. This thickness varies based on the ball diameter. In addition to the model files, I have included designs for a 3D printed mold that enables you to create your own small balls from hot glue. The video provides further information on the mold and molding process. To achieve optimal results, print the mold with finer resolution (I used .1mm layers).
