Water Bottle Opener NBF

thingiverse

I created a straightforward "water bottle opener" for my 91-year-old grandmother. It fits perfectly on the German-bottle type called "Normbrunnenflasche," which is made of glass and has an aluminum cap with precisely 45 notches. I had tried many different bottle openers, but they didn't work well for this specific kind of bottle because they lacked the exact number of notches needed to open it. Therefore, here's a very simple bottle opener designed specifically for the 0.7-liter "Normbrunnenflasche" with precisely 45 notches. Update: I have also created another version that accommodates the cap with 38 notches, which can be found at https://www.thingiverse.com/thing:2666887.
