This is a simple mount extension for Ring Spotlight Cameras. Some of the cameras I've installed around my house under my soffit needed to be lower to show more of my yard and less of my soffit. I used the screws that came with the Ring to screw the original mount to the extension. I've added 50mm, 100mm, 150mm, 200mm, 250mm and 300mm files. I used the 100mm file myself, but every application is a little different. I'd recommend measuring before guessing and printing as it can be a fairly long print.
