Massachusetts Institute of Technology Problem Set 1 2.008 Design and Manufacturing II Problem Set 1 We would like to distribute our favorite solution for each problem to the class as the official solution so please strive for clarity and elegance.

Pick a component that requires at least three different types of features (3 bolt holes are not different types of features).
