I am not sure that it belongs in this forum, but here it goes anyway. I often cary around my iPhone 7 Plus, it is the handiest "rig" I have. Even though I am looking forward to the "Volt" I tried one of the gimbals available on the market. It is difficult to walk with the system without experiencing an annoying bobbing effect. I decided to build a small z-axis enhancement based on Garrett Brown's patent (sorry). It is strictly for my own consumption, but it could be useful sometimes for other than myself, so I decided to share it. I moved the grip vertically under the center of gravity, so it is acceptable to hold without too much wrist discomfort, it's fairly small and it works.
