On one side of a grain of salt, you can put 10 skin cells, 100 bacterium, or 1,000 viruses.
This pendant began as a sort of Sierpinski tetrahedron, with a stylized “stepping” facade, and that thing was spherically inverted, but the result had too great a range of large & fine details (a common problem with inversions), so it had to be cut into two individual objects to make either one printable. The other object (from the center of this one) also became a pendant.
In the photos it’s shown with a jump ring & chain which are not included.
It was made by i.materialise where it can be purchased in a variety of materials.
