The mount that comes with G1W is just too plain. Since G1W is more or less needs to be permanently mounted. I designed a simpler mount to work. No modifications needed to the camera or car to use this.
It requires double sided tape. 3M VHB preferred. Needs to be strong enough to hold the camera. a 1"x1" square will hold up 0.25lb of force. about 4oz @FOS 5. Camera breaks my scale at 2,4oz. The tear away force will be in area of 60lbs.
For my car, 24deg incline is what it needs. your millage may vary.
set your printer to 3 shell layers. this will make this nearly 100% infill.
