Now I have lots of pictures so that you can see and understand how I've done it.
Hope you enjoy this.
Step 1: Make the USB body
Use a saw and cut the resulting piece on its lenght, then bend it until you obtain a copper plate.
From this copper plate you will cut a pice that you will bend it in an U form an a pice for the lower side.
Step 2: Make the front piece
From this you will make two pieces that have a hole fore the USB male plug. One piece goes on the front side of the USB and one is for the cover.
To make these pieces use you USB and trace the corect size on the copper plate. Next drill a hole large enough for a file to go trough. Then use the file to give the hole the correct form and size.
Step 4: Make holes for the LED and attach the front piece
After you've made the hole, solder the front piece in place and file down the excess copper and solder.
