Big Mouth Bubbler Tri-Clamp

# Problem: BMB Universal lid pops off. I like Northern Brewer's [Big Mouth Bubbler](https://www.northernbrewer.com/pages/search-results-page?q=big+mouth+bubbler) but they got rid of the screw-on lid, and replaced it with a press-on cap that pops off unless the lid and bottle are super dry, and even then it can pop-off. ... and seriously, who dries the lids, most of us pull it straight from the star-san and pop it on. This design secures the lid with a tri-clamp-ish fitting. All parts print without support, and no hardware is needed, except for an optional piece of string to prevent losing the pin. # Solution: 1. Print the 3 parts 1. Screw-on the adapter ring, wide side up 1. Press-in the sanitized BMB Universal lid 1. Attach the collar over the ring and around the adapter 1. Insert Pin to secure the collar The gasket on the BMB lid will now seal properly, so the collar does not need to be super tight, hence securing with nothing but a printed plastic pin.
