Be sure to print the bottles and stoppers in spiralized mode with a bottom floor.
The fit of the stopper in the neck of the bottle depends on the size of nozzle that you are using. This design is optimized for a 0.5mm nozzle. If you are printing with a smaller nozzle, you may want to scale the stopper up slightly to ensure a snug fit.
When printed with good filament and a well calibrated printer the bottles will be watertight.
The top rims of the bottles and middle rims of the stoppers have tiny radial slits that create a toolpath that traces back and forth over itself creating a stronger and more watertight surface than you would get otherwise.
