This is a Heart Box version of the Snowflake Gift Box.
Should be able to use the top and locking mechanism from the original as i haven't modified the size at all.
You can print in multicolor or in one plain color.
Bambu will nag about supports but i have printed this without and haven't noticed any issues.
You can print with supports if you wish, i would recommend (if your printing with supports) tree organic as it makes for the easiest cleanup.
