Zipfer beer coozie , for 330ml beer bottles

Coozie for Zipfer Beer Bottles. Snug fit. 

The vertical ribs bend slightly when inserting the bottle and prevent it from falling out.

Settings are important, especially for the cap to be secured

Petg Spiral/Vase mode

0.8 mm Nozzle

0.3 mm Layer height

    1 mm Line width 

FYI sliced with Cura 5.40, i'm not sure Prusa Slicer handles Vase Mode perimeters the same.

for the cap no bottom layers

I've added test models to assure tight fit without wasting material
