I created this flip bottle cap to prevent insects in your drinks. 

Print in different colors and mark the drinks of you and your friends. 

Works with almost any beer or limo bottle and snaps firmly into place. 

Second hole is for a Keyring, the cap itself has the size of an 1€ coin, so you can also use it as a shopping cart coin.

Really handy to always keep it on your keys as summer is about to arrive.

Attaching the lid to the base seams to be a bit hard at first, but this way it will stay attached afterwards. 

Printed in PLA, but PETG should also work with different settings.

Boosts, Ratings and comments highly appreciated! 

Hope You like and enjoy.
