Brando’s camera bag comes with screw mount
This next device is so ingenious, I can’t imagine why someone hasn’t invented it before. See this ordinary camera bag? It has a screw mount, so you can lay the camera bag flat and mount your camera on it. This contraption is perfect for self-portraits, not to mention some still shots where you would normally use a tripod.
The device is the inspiration from Brando, who makes a lot of very interesting devices. You should be able to get the special DC Protective Bag with 1/4 Inch Screw here.
