Four sizes of bottle adapter for the Yeti 16oz Colster. Either should be easily remixed, if needed, to fit your favorite bottled beverage. The large (Lg) and extra large (XL) STLs are the most useful. The small (Sm) is of limited use for very narrow necks. I included it as it may be the most useful if someone is doing a remix. All were printed in Overture HS TPU at 100% infill, topside down to build plate. No supports. These will only work appropriately with a flexible filament.
Note 10/24/2023: Added Yeti 16oz Colster Beer Bottle Adapter V2. A bit easier to use and works well with bottles like Goose Island IPA
