A basic lampshade that can be hanged from any lighbulb burner.
Tested and printed with vase mode with 0.4 width, should be quick and easy, less than 2 hours with under 50 grams of material.
Diameter of the hole is 39.6mm but if you want to enlarge one option is to use a negative volume modifier in the slicer.
Hope to find it usefull, and if you want you can check my other designs.
