circle packing on a rounded cube

Hi,

I created a pattern of circles in grasshopper and mapped it on a rounded cube. Each circle is placed in a different angle and some of them are overlapping surfaces. I only need them to intersect/be tangent to each other. It is for 3d printing.

How can I avoid the overlap and distortions? Is there a grasshopper script that can solve this problem? (maybe having an irregular pattern of circle packing)

I will really appreciate some help. Thanks!
