I would like to add thickness in 3d voronoi :)

Hello, I am asking you a question while using the grassopper.
I made a 3d Voronoi shape like a picture.
By the way, I would like to add thickness and smoothing to this algorithm to enable 3D printing.
Finally, I want to make smooth modeling like the next picture.
How can 3D printing be possible when the algorithm is modified?
I would really appreciate your reply while you are busy.
thank you :slight_smile:
