Graded gyroid slab
A block filled with a gyroid whose walls grow from 1 mm at the bottom to 2.6 mm at the top.
One expression field sets the wall thickness at every point of the block, so the grading is smooth and needs no cell-by-cell editing. This is field-driven design in five blocks: a box, the thickness field, the lattice that fills the box with a gyroid, Keep Main Pieces, which keeps only the largest piece, and a 3MF export.
