I made this to extend past wider window frames.   The round metal base can be applied to the part to hold the cam.  I would be mindful of the infil its a thinner part so you'll want to have a bit more infil to support the weight of the cam.  There is a slit on the wall mount side to run the original flat usb cable through.  The second hole could be used if you're using the piggy back feature.  The mount itself attched to the window frame with smaller wood screws.
