Laptop webcam cover I designed using TinkerCAD for my HP EliteBook 840 G5.

The cover slides snugly over the top edge of the screen to cover the built-in camera.

Print in vertical (tall) orientation so that there are no supports required. Don't forget to add a brim (build plate adhesion) to prevent the print from tipping over.

The print settings supplied are from Cura slicer version 4.2.1 for my Creality Ender 3 Pro. My print time was ~1 hr.
