Catch those annoying little flies that hang around in your kitchen.

It is such a simple model that I wasn't going to upload it, but I decided to share it because it works so well in my kitchen.

This fits into a standard jelly jar with a 2 ¾ inch ring (not the wide mouth canning jar with a 3 ½ inch ring).

The cover photo shows a 12 oz (375mL) jelly jar, but an 8 oz (250mL) jar or similar works as well.

Put a little apple cider vinegar into the jar, put the cone in, screw on the canning ring and set it in  the corner of your kitchen window sill or near your fruit bowl. The little flies go in and can't get out - they eventually fall into the vinegar and meet their demise.

I printed it with black PLA and a 0.4 mm nozzle, but just about anything should work. Clear filament might be good.
