Bügelflasche MKII (flip-top bottle cap)

You like flip-top bottles but don't want to take the beer bottles into office?
You don't want to buy blank bottles which have a flip-top but are not of same quality like those thick walled beer bottles and just don't feel right?
You like some club mate but are not happy with the screw on caps?
Then here is your solution: a flip-top screw on cap for e.g. club mate bottles.

I was using this adapter since about two months, but my own screw thread was not fitting 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 WIP cause I might want still to in crease the distance to lips a little and maybe reduce on the upper end the diameter a little. From functional point this is fully working and also already used more than a week in productive environment...
