I am teaching basics of mechanical engineering and for some of my students, it is hard to understand sections in technical drawings. So I decided to design, 3D print some objects from their workbook. Those objects will be in 2 or 3 pieces but with inserted magnets, so students can see them in one piece and separate them, simulating section view.
I used different magnets, but in most cases d6x1mm (sometimes doubled).
