Ian from Computer Freaks Anonymous found the uBITx.net website and let us know about his Nextion bezels.
He has been producing these on his CNC machine for some time now. They are manufactured from acrylic, have tapped holes to secure the display with plastic screws (supplied).
The bezel allows you to cut a rectangular hole, glue the bezel in place and secure using the screws. It provides a nice glossy finish and they can be produced in many colours. From the front view there are NO screw heads visible, adding a more professional finish to your project.
He ships worldwide, to US, Canada, UK, Austria, Germany, etc.
