Magic Magnet

thingiverse

In this mesmerizing desktop gadget, a small neodymium ring magnet seemingly defies gravity as it hovers in mid-air, expertly contained by a slender piece of shoelace. The secret to this incredible phenomenon lies in a second, cunningly concealed magnet embedded deep within the top beam. By securing a single knot at each end of the rope, the position of the ring magnet is precisely fixed. Instructions Print frame and top with a sturdy infill density of 20 to 30 percent, carefully confirming the correct orientation of the magnets before placing the magnet on top. Once completed, bond frame and beam together in a secure manner, ensconcing the magnet within. If the dimensions of your top magnet prove different from expected, merely adjust the SCAD file for the top beam accordingly.
