This is a case for your GoPro Hero 3 or 4 which you can use with the new DJI Oslo mobile. With this case you can mount and balance the Hero camera on the Oslo mobile. The camera can only be mounted facing you because of the fisheye lens of the GoPro. You can tune the gimbal 180 degrees and it works fine.
You can only print this for personal use. If you want to print to resale please contact me.
