Atom model

thingiverse

These are atom models which can be used to make molecules. A small magnet is glued to the ring and the ring can be fit in the atom, this way you can put together the atoms as you want as the polarity can be changed by turning the magnet in the ring. The atoms ae designed by trial and error rather than careful calculation, so you can certainly improve tehm, that's why the SCAD files are also included.
