A ring of five cubes cut and joined in Geogebra.

You can see the approximation’s fault on the right. With paper models, the error is less noticeable.

The dodecahedral version with 30 cubes is harder to model as Craig Kaplan has noted: "because you can let the laws of physics absorb and distribute the mathematical error inherent in the [physical] construction. To build a computer model, you must make explicit decisions about where that error should go. For example, the faces could be made slightly irregular, or slightly non-planar." https://isohedral.ca/a-molecular-near-miss
