Summary

Use it for that special rose or....

Use the vase for small messages of love. Write them down put them inside and if you ever want to know what's written you'll have to smash the vase.

Use supports for printing and at least an overhang threshold of 40° to ensure that no supports are created internally (the heart shape already has support inside the vase, but it needs to be supported externally).

Scale and use your own prefered print settings. (60% is about 160mm/6,3inch high)
