Bottle Cover to keep insects out

thingiverse

This cap simple sits on the bottle. It has no thread and it does not snap in. It is meant as a protection against insects. It does not close airtight. Suitable for beer-, juice-, lemonade- and water-bottles with crown caps or screw caps. Easy to clean. One-handed operation: Lift the cap and hold it between the index finger and the thumb. Then grab the bottle with the rest of the hand and drink. Drink and drive. Print with PET-G. Set up your slicer to detect thin walls.
