Decided to model a Meissner Tetrahedron after being fascinated by Shapes of constant width.
For a little bit of background read this:https://en.wikipedia.org/wiki/Reuleaux_trianglehttps://en.wikipedia.org/wiki/Reuleaux_tetrahedronhttps://mathworld.wolfram.com/MeissnerTetrahedron.html
So, basically you can put three of these same-sized Tetrahedrons under a book, roll the book over them and the distance between the book and the table will always be the same, exactly as when you use three sphere of the same diameter instead of the Meissner Tetrahedron. This is the most simple non-mathematical way I can explain this =)
