I needed to mount my Akasa Action Sport Camera above and beyond my underseat bag so that the Power Bank battery could be placed in the rear pouch of the bag and a short USB cable could be run from the battery to the camera. So I designed this simple 130 mm extension that connects GestoPlastico's (https://www.thingiverse.com/thing:2598431) seat rail clamp to the camera mounting hardware. The extension rests on the bag for added support.
