GoPro or Phone or iPad selfie stick or car back seat mount

For the phone/iPad mount use rubber bands so that it gets pulled together. For the car mount, also use 4 rubber bands (one in each corner) that gets strapped to the two hooks on the back side. To mount on a car, put the bands the headrest holders and onto the hook. You also need M5 x 35 mm screws and a bunch of M5 Nuts (ONE FOR EACH PART THAT YOU PRINT EXCEPT THE HOLDERS)
