Unfold component creating overlapping pieces

We are working on transforming our partition into its component parts for laser cutting, but are having some trouble with the Unfold command you showed us in class. As you can see in the last photo, the planes are overlapping in some places. We tried to change the sliders to space things out, but no luck. Do we need to spread them out in Rhino? Could you make a recommendation?

Thanks,

Jin and Lily
