Voronoi 3D skeleton

Hi all,

Do you know how to create Voronoi skeleton(spaces between Voronoi cells)? I’ve created Voronoi cells, but I want to generate the skeleton instead of the cells. I’ve tried solid difference, to subtract the Voronoi cells from a solid cylinder. I found that the top and bottom of the cylinder looks good, but the center (internal cells) didn’t show up. May I know how can I solve this issue? Thank you.
