Bierflaschen Deckel (Beer bottle lib)

A very simple beer crate lid for German beer bottles. 

Easy, quick and inexpensive to print. Keeps the carbon dioxide in the bottle and wasps out. 
The lid is simply pressed onto the opening with a firm click and that's it. Ideal for festivals, parties or for a nice barbecue evening outdoors.
