I was looking for alternative USB lightning cables for the cell phone tray in my Model 3, and these fit perfectly. Just sharing the info in case anyone else is looking for the same thing. They fit through the holes and sit in the grooves. Note that the USB end of the cable is also L-shaped. $10.99 for a 3-pack.
