About this 3D model

This is a remix of oiseau's smooth heart. I mirrored the bottom plane to make the heart fully rounded, smooth and “balooned”. This of course creates some complications for printing. I recommend printing straight up, upside down with just the two tips touching the bed. With a brim it should not even need supports. You should also draw on the seam along one of the edges to make it even smoother. Good luck and happy printing.
