How will it all fit together, as a USB...?

Just thinking about the dimensions of my final design and trying to visualise how it will look. I've realised internal supports/ architecture will play an important part in how it all fits together. I've been sketching out how the PCB will fit into a recess in the main body of the USB and the thickness of it, in order for it to fit securely.

Still working on sketches etc, so not posted these up yet. But my final USB design is to be in the shape of a Lipstick.
