Can we connect the cubic diamond structure structure with thicker bonds and thus reduce the number of cubic diamond structures that make up the chair?
Can we make this chair more stable by using crystallon?
I think what you might be describing is a lattice skin? There are many ways to go about doing this.
The simplest was is to remesh the surface using “triremesh”. Then you can connect the lattice to the lattice skin in a variety of ways in the “modify” toolbar of crystallon. The PDF documentation describes each of these tools and there are example files included in the download.
