This is a small lampshade for the Ikea Jansjö lamp which snaps onto the head and rests there pulled down by gravity. You can print it with different colors for different moods.
Technical
Print this with the "spiralize" option turned on. You'd need a fairly well leveled printer because the first layer doesn't have a lot of contact to the heated bed. You might use a bit of hairspray to improve adhesion or print with a brim (although a brim is ugly and hard to remove).
I have attached Cura 2.3.0 profiles for the Ultimaker 2+ and the Ultimaker 3.
