Building Porous Foam structure using grasshopper

Grasshopper

Hello I’m just new with Rhino and grasshopper program, just started it one week ago

I’m trying to make a porous structure where I can change the pore sizes so I could run a simulation

where I read the article form this link

" Design and Compressive Behavior of Controllable Irregular Porous Scaffolds: Based on Voronoi-Tessellation and for Additive Manufacturing"

However I tried to follow the steps got really got stuck at the start

the image is below, I tried using almost every voronoi cube in the forums but it didn’t work out so well when I tried to build a mesh, can anyone give me a little help here?

Thanks

Use 3d Voronoi
