This is Her Majesty’s Tessellation (own design) folded from a 64×64 diagonally rotated grid. The spacing between molecules is less dense than in the 32×32 grid-based version in order to match the different grid size.
Original pictures of this model, taken in 2018, were of not-so-great quality, so I later reshot the model in 2020 using a better camera: that’s why multiple pictures show the same view. Since the model spent the two years in between hanging in a frame on my wall, you can also see how the shaping has changed by itself, with the molecules opening up more. This change could be temporarily reversed if needed by flattening the model under a heavy weight.
