Lampshade with notch for screws

This lampshade has a notch to be held in by screws inside a light fixture.  Worked great in my bathroom fixture. Extra thick rim near top for strength at connection to fixture. No support needed if printed small-side down. Use only LED bulbs and hi-temp plastic like ABS or PETG, not PLA. If you try to use halogen/incandescent bulbs the plastic may melt.  Please be safe.
