Is there anything in the camera mounts to stop the cameras falling out? I’m a bit worried about them dropping from 6m!
Usually the housing on the mount is tight enough to hold the camera firmly. If you want you can wrap the camera to the mount with a rubber band.
I had my tripod fall over this past weekend on a game (luckily at halftime) and they didn’t pop out till the pole hit the wagon and suffered no damage. They fit tight in the 3d printed base and it was my fault for forgetting my wide base tripod and had to use what I could find at Lowes.
