Using white card stock, scissors and some glue, Horst Kiechle created an anatomically-correct model of the human torso with removable organs. Now you can too!

The resulting model comprises multiple chambers, pacemaker clusters, epicardial membrane and endocardial lining, all meticulously designed to mimic the structure and functions of the human heart.

Science Astounding 3D-printed human heart model cuts and sutures like the real thing The full-size, life-like model could give surgeons a chance to practice their life-saving skills.
