Had an issue earlier this evening with annoying as hell Fruit Flies. I whipped this up in under 10minutes to attempt to deal with them. It surprisingly worked a lot better than I thought it would; I got probably 40 of them within an evening.

** Filled with Apple Cider Vinegar to about 40%. **

There are two options for this model.

1. the Solid Model can be printed if you like, but it will require interior supports to hold up the top. But that's not an issue as those supports would be on the inside. Id suggest a support angle of 76-80 degrees would be enough, It's just the center that needs support.

2. The split model. This has the added benefit of being able to remove any supports, but you'll have to secure the top and bottom halves with spots of hot glue, or small pieces of tape (or you could just rest the top half on top of the bottom, as it's not supposed to be disturbed or touched anyways to be effective.

** Make sure to print with at least 3 shell/perimeter walls in order to maintain its water tightness. **

Due to how well this worked, I will probably clean it up and address some of the model issues shortly.
