Dove Tail magic box
thingiverse
I redesigned the original design in Tinkercad. I made it into a box with some space to hide something (like money as a gift) I also designed it for a 9.6 mm ball and a 6mm by 3mm high round magnet that I could buy at my local office supply store (white board magnet). The dimensional tolerances are critical, I had to sand a bit to make parts fit together smoothly. Maybe I update the design later. Let me know your experience when you print this design. Also have a look at the original design from ScienceMadeFunner and the Clip on how to use the puzzle.
