Laser cutting model

In Developing the final cell-structure model as my proposed geometry for my laser cutting model, in order to cut and organize the model, i have decided to arrange points of intersection between each surfaces.

Each of the surface have been set an offset in order to create a intersecting surface between each circles. However, the closest i could get in designating points of intersections was slim. Some of the points appeared to be appearing where the surfaces intersected, and some were far off from the intersecting surfaces.

In consultation with my tutor, the initial idea in creating a set of intersection points didn't go too well, and started on a new idea of creating contour layers within the cell-structure.
