A lid for a container for catching fruit flies.

Print this thing out. Put some fruit in a cup. Put this thing on the cup with the cones facing down. Fruit flies go in but they don't get out. There are no threads on this... it just sits on the cup, so don't knock it over when there are flies inside!

V3 is the thicker part... I found the older one was a bit fragile. But the thicker one uses more filament, so I left the old part available for upload in case you want to try it.
