Looking for a medium to large assembly in Solidworks with nested sub-assemblies

Hello-

I'm building up a demo for a new software application that can visualize nested assemblies in the same model structure that it was built.

Specifically, I need a top level assembly that has some nesting of sub-assemblies and components.. see below:

0 - top level assy
1 sub assem 1
2 comp 1
2 comp 2
1 sub assem 2
1 sub assem 3
2 comp 3
2 comp 4
3 comp 5
3 comp 6

etc.....
