Pacemaker

thingiverse

We were approached by a group of students who were undertaking a Medical-themed project within the Technology Student Association initiative. The students required an accurate representation of a heart and a pacemaker, which would serve as integral components of their innovative device. Our initial search on Thingiverse led us to discover an existing 3D heart model; however, we also realized that a custom-designed pacemaker was essential to complete the project. To achieve this, we leveraged Autodesk Inventor 2015 and successfully created a bespoke pacemaker. Upon completing each part, we employed a soldering iron to carefully drill holes for two 12" copper wires, which we subsequently secured using hot glue. This intricate process resulted in a functional anatomical heart with a precisely engineered pacemaker attachment. The steps taken to design this pacemaker in Inventor were methodically approached. Firstly, an oval base was established, followed by the addition of a rectangular structure that required precise dimensional control on the top edge to ensure it measured exactly 1" in length. Through further modifications, the model underwent trimming and extrusion, culminating in a thickness of 1/4". To enhance the design's overall aesthetic, we applied an 1/8" fillet to all edges. To facilitate seamless modification of our Inventor file, it has been made available for editing purposes.
