Wine Bottle 5 Liter Screw Cap

thingiverse

I was searching for a screw cap to fit my 5-liter wine bottle perfectly. Since this large bottle is super convenient for collecting natural spring water from the forest with ease, I decided to design and print my own custom-fit bottle cap. This DIY project will likely work well for most standard 5-liter wine bottles found in Europe. Feel free to give it a try and share your experience with me! For optimal results, I highly recommend adding a food-safe seal of exactly 34.40mm in diameter and 1mm in height into the cap before use. Without this seal, the water will slowly leak out of the bottle over time. After multiple uses, you'll find that the cap becomes incredibly smooth to handle.
