Had an old Sconce/carriage light fixture and needed a shade.
This is a typical Landlord special big box cheap fixture. 80mm opening with set screws.
I've included a test print so you can make sure it fits. And also if you may need interior supports.
Note: File varies slightly from the installed light.

Experiment with the test and see if you need supports. Also to test fit your fixture.
