A functional, 3D-printed railway pump car, designed to be portable and easy to assemble, has been created. This mechanical contraption mimics the seesawing beam motion of traditional handcars to propel itself on tracks. For engineers and makers, this project demonstrates creative applications of 3D printing for functional, interactive devices and highlights the challenges of designing for transportability and collaborative use in mechanical engineering.
