AirTech Home Automation - Nest Hello Wedge Extender Kit - WHITE (Classic Pill) - 30° to 45° angle

How far out does it extend ?

Does this fit with exiting holes that come with nest mount? Or would I have to drill more holes?

Does it really fit the 2nd gen wired Nest? I just got mine and the Nest backplate is too flush against the wedge to attach the camera.
