Description
This is based on this canning jar lid: thingiverse.com/thing:19105
The fly trap lid pictured was printed with a low, draft resolution on a Mosaic with ProtoParadigm Red PLA.

Instructions
After printing, put some bait in a canning jar and screw the lid on. This bait can be pieces of fruit, fruit juice, or anything else that will attract fruit flies. As luck would have it, I haven't had any fruit flies around since I finished this (not that I'm complaining), so I haven't had a chance to test it, but I've had good luck with cruder traps of similar design in the past. Apparently a mix of some fruit juice with just a little bit of vinegar in it is a decent bait.
Place the baited trap near where you have fruit flies. They should enter through the hole at the end of the inverted cone, and will be unable to escape.

You have no fruit flies after you made the trap? IT WORKED!
Seriously, though, what tool did you use to make this? I love the threads on the inside of the lid. It also makes pretty music when printing.
Oh, also, I didn't mean to be deceptive, I've updated the text of the thing to be clearer that I haven't had a chance to test this yet because I haven't had any fruit flies, but traps that work by the same means have worked well for me in the past.
I designed this in openscad. I try to take a somewhat modular approach to design, so this also depends on http://www.thingiverse.com/thi... which is the lid with the threads. The threads were designed from caliper measurements, and implemented with this thread library for openscad: http://www.thingiverse.com/thi...
I'm glad you like it. :)
Nice! I have used vinegar, a drop of syrup and a drop of dishsoap to remove the surface tension seem quite effective. I guess one could smeer some syrup around the middle of cone to get some to stick around incase of an Houdini.

Any chance you could upload a Makerbot-friendly file? When I use ReplicatorG, I feel way over my head configuring the infill and shells. I am new to all of this.
Thank you for your consideration!
