How to Make a 3D Printed Heart Mechanism and Plush Jacket

I wanted to make a realistic animatronic heart, and as I was developing the 3D printed mechanism I used a sock to try and get a vague idea of how the silicone skin would move once the design was finished. Since the silicone casting turned out to be quite challenging and very expensive, the sock test gave me the idea to instead use a slightly elastic fabric to make a plush heart design, which could be fitted over the 3D printed mechanism.
