This is a simple camera cover for the Macbook Pro. There's very similar designs out there but none of them were a good fit for my machines. These are for the 2021 16" and 2023 14", they are very slightly different sizes.

I've included the parameterized .f3d so you can easily modify the dimensions if neither of these fit your machine. They should snap on over the small lip of the lid and be easy to slide over for when you want to use the camera.
