Insert the Female end of the USB extention (the part that doesnt connect to your computer) into the hole you just drilled.
Then just apply the glue/epoxy and let it sit for 24 hours. This Creates a strong bond between the plastic and metal. I used some tape to help hold the connecter in place while the glue cured. Be sure to apply glue to both sides of the connecter. Once thats dry the next day, zip tie 2 of the metal "ears" so they wont fold in on themselves when you use it.
