Mason Jar (standard mouth) Fly Trap Lid

Found a model by GeekToybox, but since I didn't have a wide mouth mason jar, I had to design my own (forget buying new jars, just resize the lid to fit what I've got). So after I had printed the design featured here: https://www.printables.com/model/75161-mason-jar-fly-trap .  I went about designing my own variant just using the printed dimensions that wouldn't fit in my jar.  But now, any of those out there without a wide mouth mason jar can have a very simple fly trap lid to use.

Just find your preferred solution to put in the jar, and let them little buggers come in, but not be able to escape!

I had printed mine in teal PolyLite PETG, using 0.2mm layers.
