I designed this to easily hold the PS3 Eye camera on the Ender 3 V2 without any extra hardware and while being easy to remove.

This attaches to the X-axis of the printer. You just have to slide it on! It has room to pivot in case you want to adjust the rotation angle a little bit.

Two of the images show the camera's viewing angle with the camera's two different field-of-view options.

There is a "tight" version and a "loose" version.
Both versions work well, though I recommend the tight version unless you want some wiggle room.

If you're curious about the print settings I chose, you can look at the attached photo.

There is a picture of the print settings I used. This requires very simple supports, so you might be able to print it without them.
