Flytrap

A fly trap to be placed on top of a mason jar filled with apple cider vinegar to catch fruit flies. The pointed end goes down so they can guide themselves in through a 4mm hole in the center and then they can't find their way out. Additionally, if you flip it over, you could use this as a dispenser for glitter or other granular materials. This is for regular mouth mason jars, not wide mouth. The stl for this was created in MS Excel with 200 radial segments of 14 facets each as a proof of concept. Feel free to download, or contact me if you do Excel and want a copy of that.
