1. A 3D printing pen drawing template in a form of a modular modelling kit for drawing geometric structures corresponding to models of chemical molecules, the modular modelling kit comprising a plurality of construction modules,
wherein each construction module of the plurality of the construction modules comprises:
a base that is flat, at least one post that is vertical and protrudes from the base, with a contact point at an end of a free tip of the post,
connection means formed at the base for connecting the base with the connection means of other construction modules of the kit,
and wherein the plurality of construction modules comprise the following construction modules adapted for drawing the models of the chemical molecules:
a) an sp3 start module for a molecule model with sp3 or tetrahedral geometry, having a T-shaped base and four posts with contact points for three exterior atoms connecting to a central atom;
b) an sp3 left module for a molecule model with sp3 or tetrahedral geometry, having an L-shaped base and three posts with contact points for two exterior atoms connecting to a central atom;
c) an sp3 right module for a molecule model with sp3 or tetrahedral geometry, having a shape corresponding to a mirror shape of the sp3 left module;
d) an sp2 start module for a molecule model with sp2 or trigonal planar geometry, having an angled base and three posts with contact points for two exterior atoms connecting to a central atom;
e) an sp2 left module for a molecule model with sp2 or trigonal planar geometry, having an angled base and two posts with contact points for one exterior atom connecting to a central atom;
f) an sp2 right module for a molecule model with sp2 or trigonal planar geometry, having a shape corresponding to a mirror shape of the sp2 left module;
g) an sp2 both module for a molecule model with sp2 or trigonal planar geometry, having a three-spoke star-shaped base with one spoke longer than the others, and one post with contact point for one exterior atom connecting to a central atom;
h) an sp start module for a molecule model with sp or linear geometry, having a straight base and two posts with contact points for an exterior atom connecting to a central atom;
i) an sp both module for a molecule model with sp or linear geometry, having a straight base and one post with a contact point for a central atom;
j) an end module being an end module for any molecule model, having a straight base and one post with a contact point for one atom.
 
7. A method for drawing, by means of a 3D printing pen, geometric structures corresponding to models of chemical molecules, the method comprising the steps:
providing a 3D printing pen drawing template in a form of a modular modelling kit for drawing geometric structures corresponding to models of chemical molecules, the modular modelling kit comprising construction modules, wherein each construction module comprises:
a base that is flat, at least one post that is vertical and protrudes from the base, with a contact point at an end of a free tip of the post,
connection means formed at the base for connecting the base with the connection means of other construction modules of the kit,
wherein at least two construction modules differ from each other by a configuration of posts and at least two construction modules differ from each other by a configuration of connection means,
connecting a plurality of the construction modules to form a particular drawing template;
using the 3D printing pen, drawing straight lines connecting contact points of the vertical posts of the connected construction modules.
