For YAAK Cube

[ggaliens]

1) Make Voronoi tidbits.
2) Cut all tidbits with faces of cube (polyhedra as cutter on slices submenu)
3) Be very very careful during required cleanup of (2). It becomes easy with some experience.
4) SEW all faces on outside together using manifold face stitcher.
5) Do cleanup on step (4) such as deleting small edges. If you don't like so much cleanup ... start with MONO-DISPERSE foam (look in my sample files that come with plugins)
6) Use bevel-intrude macro that comes with manifoldlab.
