Art Deco Hanging Shade

Bare bulbs are annoying, and I wanted to experiment with translucent filaments, so I designed these lightweight lampshades for the hanging bulbs in my apartment. They are attached by a mounting plate that slides over the fixture's threads and is clamped in place by the fixture's threaded sleeve (see last picture). The threaded portion of the fixture has a Ø28 mm, with a 26 mm flat cut into it, but I've included the .stl for editing to fit your own fixture.

These were printed at 0.35 mm layers to save time during tests, but I would reprint the Lampshade at 0.20 mm to reduce the amount of drooping I had on a few of the extreme overhangs. Otherwise, I was very happy with the results!
