Solid Anatomical Heart

thingiverse

I designed this solid heart from a freely downloadable object that had some messy interior meshes which took a lot of time to eliminate. Now it's watertight, but printing this design is still a challenge and finding the right orientation has proven difficult so far. If you figure out an angle that works for you, please let me know. You can choose to 3D print the entire model (heart.stl) or break it down into two separate parts – top and bottom – and then attach them using connecting pins.
