Flowing 3D Printed Parametric Artwork

I made some 3D printed panels to decorate boxes of storage I made. I used Grasshopper and made two definitions : the first to make curves from the path of particles influenced by attractors, placed according to the photo (Modified version of Generatives Landscape's agent steered by fields definition), and the second to make the volume, with custom sized pipes following the curves.
