Glass Soda Bottle Screw Profile

thingiverse

Using a glass pepsi bottle as a reference, I modelled the profile of the glass screw top on the bottle. I've included a profile reference STL, as well as a 'cutting tool' version which is expanded slightly. You can simply difference out the 'cutting tool' shape from a solid block and have very precisely fitting strong mount on to common screw top glass soda bottles, including those sold by pepsi and coke in many countries. I originally designed this component as part of a project to be able to carbonate glass soda bottles inside a home carbonating machine that normally accepts only plastic bottles.
