Wide Mouth Ball Mason Jar Thread Cover

thingiverse

Mason jars are super quaint and hip to drink out of now, but those pesky threads around the opening are a major turnoff. I'd be on the bandwagon if it weren't for that uncomfortable annoyance. I created this part to cover those threads and give you a smooth surface to rest your lip. It's designed specifically for wide mouth jar openings. Big thanks go out to oldwizard and his thread part files - thing:173670 was a huge help!
