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!

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.

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.
