Fruitflytrap

thingiverse

This is a cleverly designed trap that snugly fits onto 65mm glasses. I crafted it specifically for jam-filled glasses, cherry-stained glasses, and other everyday glasses. Noteably, it lacks a thread, rendering it unscrewable. Printing it with dark, non-transparent materials proves particularly useful, as the light emanating from within the glass serves as an irresistible attractant to pesky flies.
