dovtail puzzle box

thingiverse

I own this box with wood, but can't recall where to purchase it. So, I printed one as a gift for puzzle enthusiasts in my family. To assemble the box, you will need two neodymium magnets measuring 5 x 1mm (do not use stronger magnets - they won't work) and a steel ball with a diameter of 9.5mm. I used 9.5mm steel balls or marbles for this project because I had an abundance of them from the 3D Printed Marble Machine #3 designed by Tulio. P.S. I discovered a solution video on YouTube - search for "The Impossible Dove Tail Box".
