Although other Voronoi hearts exist, this is my take on it. I call it sparse since this model seems to be less dense than the other existing ones which I would call dense.

Printing Information:

• Use tree support to support the voronoi structure, you can get away by only supporting the critical regions.
• Use a brim, since, even if the model can stand on its own, its contact surface with the printbed isn't all that much.
