Voronoi3D and delete edges from cubic

Hi, I need help.
I want to create a model using Voronoi 3d and tried it like the picture.
But, I want to delete the edges from cubic(303030).
Is there any good way to do this?
Also, I want to be able to handle different seed values.
Thank you for your time in advance.
