Fruit Fly Trap Jar

Many of the fly trap designs seem hard to involve reused bottles. Those bottles are not always the same size, so the models may need to be resized to fit. Tedious. Bottle based traps are also easy to tip over, causing a smelly mess. I think this design improves on all that.

YELLOW. Print the lid in yellow. I used clear for the jar.
