Heart with void for small gift

I downloaded the original low poly heart but can't find it again to give credit - I'll happily re-upload as a remix if anyone knows who did the heart I based this off

I printed with the halves vertical for the rainbow effect, but printing with internal faces on bed will give a cleaner print
