Know someone with a big heart and a good sense of humor? Give them this anatomically correct Voronoi heart to show that you care, and also that you’re a little weird. Either way, it is sure to put a smile on their face!

The Voronoi surface follows both the inner and outer surfaces of the heart, so the inner walls of the ventricles and atria are present. Valves have been removed, so there are holes passing between the cavities.
Internal supports have been added, especially for the bottom of the inner wall of the left ventricle that would start printing in mid air otherwise. The supports are barely visible in the finished print, so they do not need to be removed.
You will need to add outside support for the overhangs of the pulmonary veins. You will also need some general support for the area around the apex. The “Tree” supports in Cura work well for this.
The other pictures above show an example of a “Big Heart Award.” The printed piece is mounted on a block of dark walnut. The vena cava is just right for a bundle of flowers, and the ventricles can hold small chocolates. This particular award went to a big-hearted frontline healthcare worker during the COVID19 pandemic.
