Model
This 3d model is a building set to make your own atoms and molecules. You can differentiate the different atoms by color and size. I made sure to model 2 different sizes, hydrogen is commenly used as a small atom.

To make an atom you print both halves, which you can easily connect with a small piece of 1.75mm filament. You can also combine the two halves by gluing them, but this is optional.

Each atom has 6 holes where you can use 1.75mm filament as a connector between the molecules.

Measurements

The small molecule has a diameter of 15mm.
The large molecule had a diameter of 20mm.
 

Molecule printing:

I got the best results with printing by object instead of printing by layer, this reduces the amount of atom halves per build plate but increaces the quality. Feel free to print by layer if you want more atoms on one build plate!

If you have any questions about the model or if you would like a customized version, please feel free to contact me!
