Self-Assembly
Self-Assembly is the emergent property of order arising from disorder.
https://en.wikipedia.org/wiki/Self-assembly
I first found out about Self-Assembly from Steve Mould's video found here:
An interesting website for learning more about virology:

Inspiration and motivation
There a few models out there besides this one that also are meant to demonstrate Self-Assembly, but I found that they either required specific magnets or were hard to print using FDM printers (needed supports etc…). I decided to make a model from scratch that had FDM 3d printing in mind from the start. Models I took inspiration from: https://www.printables.com/model/334972-self-assembling-virus-dodecahedron, https://www.printables.com/model/460385-virus-in-the-third-dimension-the-art-of-self-assem. The idea behind this model is that it would be easy, fast and cheap to print, and wouldn't require glue, yet still manages to self-assemble.
Parameters of the parametric fusion360 model:
| Name | Purpose | Default |
| pentagon_diameter | Diameter of circle from which pentagonal prism is inscribed. | 16mm |
| pentagon_height | The resulting height of the pentagonal prism. Each side of the dodecahedron will have this depth. | 6mm |
| magnet_height | The height of your preferred magnet. | 2mm |
| magnet_width | The width of your preferred magnet. | 3mm |
To change parameters:
- open the .f3d file in fusion360
- under solid toolset, click “modify” dropdown
- click “Change Parameters”
