Ultimate fruit fly trap

I hate these little flies in the kitchen, no matter how much you keep it clean, there are always a few of those tiny buggers hanging around the fruit. I used to make a cone out of paper but I decided to 3D that thing and make it re-usable.
Just put a bit of fruit in the glass, put this catcher on the glass and make sure you're outside when you open it.

Fits most glasses, dimensions are approx: diameter 8.5 cm / 3.335 inches, height 7 cm / 2.75 inches.
I printed in PLA and no supports are needed.
