Cut out a piece of styrene for each foam piece, and hot glue them together. (Careful with the glue - if you use too much, it will actually melt the styrene and you'll get ugly bubbles.)
After that has cooled, trim the foam down so you can't see it poking out from under the styrene. I usually cut a little bevel into like, like you can see in the photo.
