voronoi minimum size component/setting?

Hello,

I have been working through Grasshopper tutorials and have an OK understanding of it although some of the terminology I don’t know as well as functions.

As I am new I am voronoi crazy – sorry.

 Question%201%20circles.jpg

I was wondering, is there a component or setting to control the minimum size of voronoi structures? I have highlighted what I mean in the picture with the red circles. I want to create a minimum thickness e.g. it never goes below 5mm at any point

Thanks for your help!
