I got a camera for FPV (First Person View) for my quadcopter/drone. The camera sends live video back to a screen to see from the drone's point of view. I asked the salesman how to attach it. At that time, a folded piece of duct tape held the camera to the mounts. I decided to create my own 3D-printable bracket that attaches directly to my quad-copter (I have a DJI 330 Elegant Quadcopter) using zip ties. The camera sleeve fits a camera with the dimensions of 30x30x12.5mm in the main body and a lense with a width of 16mm.
