Freeplay CM3 port cover

Just assembled an awesome Freeplay CM3 and the only thing I've found that I don't like so far is the way the top of the unit looks around the CM3 ports.

This covers the open areas and makes the entire top more uniform. All of the ports are still usable.

I forgot to cut off the raised letters on the top of the GBA prior to install. It would sit more flat if I had. Glue would also help, the one in the photos is not glued.
