Blender Edge Problem...

I have this odd problem in blender, I apply the edge settings for my floppy disk (It is a "saving file..." indication.) but it only does the outside, what I want is the inside of the disk, where the white sticker should be and the silver metal slider thingy... They are all seperate meshes, so they can be done, someone has done it before but didn't tell me how.

Just wondering if possible and if it is can someone point me in that direction.
