Here, the carriage and tool represent two independent entities that will disconnect and reconnect numerous times. Each reconnection must &#039;&#039;repeat&#039;&#039; to the same position relative to each other regardless of the cycle. By exact constraint design principles, the (six) degrees of freedom of the free tool plate are constrained by the same number of constraints. Doing so joins the two entities in such a way that they can neither bind nor wiggle. They only fit together one way.<br /> <br /> The &#039;&#039;Maxwell Coupling&#039;&#039; is a mechanical design pattern for fully constraining two entities with six points of contact. In the ideal case, the two entities join together and infinitesimally small points. This principle puts a high stress on a small surface area, so, in practice stiff materials such as steel are used to form the coupling points.<br /> <br /> == References ==<br /> * [http://pergatory.mit.edu/kinematiccouplings/documents/Theses/hale_thesis/Examples_of_Exact_Constraint.pdf Kinematic Couplings in Optics]<br /> * [http://cba.mit.edu/docs/papers/17.03.peek.pdf PopFab: a Case for Digital Fabrication]<br /> * [https://github.com/e3donline/ToolChanger E3D Toolchanger Tool Plate and Carriage Documentation]<br /> * [https://www.youtube.com/watch?v=cfSHss5j5KU 3D Printing a Kinematic Coupling]</div>
