Description:
Molecule set for Sodium chloride, Water, Ammonia, Methane, Carbonic acid and Ethanol.
The source contains atom models with holes suitable for building simple molecular shapes.
The most common shapes with up to 6 bonds are supported.
See https://en.wikipedia.org/wiki/Molecular_geometry.
Source for OpenSCAD is provided.
Instructions:
Common matchsticks are recommended as bonding material.
It is important to trim the hole diameters before printing the full set.
I recommend adjusting the hole diameters in the source instead of scaling the STL models.
Start by printing carbon_4() and trim bottom hole for a perfect fit (parameter hole_d0).
Also trim the hole diameter for the rest of the holes (parameter hole_d1).
The reason for using two parameters is to compensate for deformation during printing.
Holes not facing directly downwards usually becomes a bit larger (and slightly oval).
When done, print the full set according to the list be
