Simple and effective fly trap

Most fly traps are for fruit flies. This is an OUTDOOR trap for house flies - the kind that buzz around fast. The key is rotten shrimp. I wanted something I could easily make and then dispose of. This only uses 6g of filament and prints in 23 minutes on an A1. After printing cut a hole the size of the cone in the lid of a disposable container. I used a takeout soup container.Fill about ½ way with waterAdd a piece of shrimp, ideally rawadd a drop or two of dish soapPlace it in the sun to help it “marinate”Should start noticing flies in about 2 daysDispose of the whole thing (in a bag!!) once the layer of flies is pretty thick
