Step 2: Making the Strap
For the strap that holds the camera to the gun, just take two long pieces of tape (one longer then the other one) and put on each other so they glue together. There you go!
Now it's possible the lens is a bit to the right or the left, so just look at the opposite side of the lens position (example: if your lens is to the right, look to the right of the screen) .
