This simple box was a meant as a educational project for my son. We worked together to get all the measuring done and discussed and improved the final design after some paper templates and a test cut on the cnc.
I used my desktop cnc-machine by Stepcraft and a spiral-toothed 2 mm flute. After sanding I used hard wax oil to give the box a nice finish. Four neodyn magnets hold the box together.

I haven't tried to print the stl so be careful and let me know if there are any issues.
