About this 3D model
It was designed as a beer cap, but theoretically fits any standard bottle.It is not water resistant or beer resistant d-_-b.I used PETG so I used a scaling of +1.2% and it fits perfectly. (it depends on the material used; somewhere between +0.8% and +1.5% for PETG). I do not recommend printing with PLA if you want to keep the beer somewhere in the sun or in the fridge.
