Smartphone GoPro Mount Offset Tool
thingiverse
Heliox made an excellent hair-tie based clamp to mount a smartphone to a GoPro mount: https://www.thingiverse.com/thing:2368959 I use a GoPro style mount with a suction cup to mount my phone to use for navigation. Because of this I want to block the least amount of the windshield as I have to. The original design attaches to the GoPro mount on the side, which would visually place the phone right next to the "arm" of the suction cup. This piece is specifically designed to interface with Heliox's elegant design and will center an iPhone X on the suction cup arm. For use in a car I would recommend ABS or PET-G over PLA (which will likely warp in the summer weather)
