This is a Cap for Beer Bottles e.g. standard Beer Bootles in Germany (DIN 6129 Glas Bottles)
.2 is by far enough but if you want .08 its better :-D
The stl is blank without the text maCyo. You can add Text in your fav CAD SW or bei adding text in the slicer of your choice.
Update 20231003: One Day is enough for Version 1, Version 2 is online :-)
Little but effectively change at the front. 2mm extendet for better pushing the Cap from the bottle.
happy printing
