Bügelflasche MKII (flip-top bottle cap)

thingiverse

You enjoy flip-top bottles, but don't want to bring beer bottles into the office? You're not satisfied with blank bottles that have a flip-top but aren't as good as those sturdy beer bottles and just don't feel right? You like some Club Mate but are unhappy with screw-on caps? Then here's your solution: a flip-top screw-on cap for Club Mate bottles. I've been using this adapter for about two months, but my own thread didn't fit properly so it was hard to handle after some time as it wore out quickly. After finding part https://www.thingiverse.com/thing:1685815 which fits perfectly on bottles, I decided to make a MKII of the adapter. Please note that to increase the distance from your lips to the screw adapter itself, I did cut off 5mm of the screw thread. This is a work in progress because I might still want to increase the distance to lips a little and maybe reduce the diameter on the upper end a little. From a functional point of view, this is fully working and has already been used for more than a week in a productive environment...
