Task · part of 6. Invent something: users first, then the design, and start the notebook
6(b). Make a model, and list what a working prototype would need
Required
Clay, cardboard or any readily available material, plus a list of the materials a working prototype would take. That list is what requirement 7 builds from.
Notes and warnings
Note. The materials list is not decoration: requirement 7 builds a working prototype, and this is where you work out what that would take. A model in cardboard whose real version needs machined parts is worth discovering now rather than after the approval.
