Stacked circle packing tubes on existing 3D mesh (ImageCircles)

Hey all, I’m attempting to create a 3D sculpture to be made of 3" wide tubes that are 4" tall. What I want to know is if there’s a way to import a 3D mesh of an object to use ImageCircles to make it look as close as possible to the exterior shape. Basically slice the model into 4" vertical sections and take the exterior sliced curve of each section to use as a base for tangent circle packing.

If you guys know of anything that could help do this in grasshopper i’d really appreciate it!
