Fidget Molecules

This collection of atoms uses swivel snaps to connect, forming twistable organic molecules that are fun to play with and can be used as a learning tool to demonstrate the shape and movement of organic molecular structures.

The pictures above show all atoms in white, but you may choose to use different colours for different atoms.

The focus of this set is on the four main organic elements (carbon, nitrogen, oxygen and hydrogen), but with a bit of imagination they can be used to represent other atoms as well.
For the sake of simplicity, this set treats double and single covalent bonds the same. This means that a carbon atom with one double and two single bonds uses the same file as a nitrogen with three single bonds because both atoms are bonded with three others and have a similar trigonal pyramidal shape. You may choose to print them in different colours though.

In order for the atoms to fit together pro
