Pocket Cribbage Board

The Compact Cribbage Companion is an innovative design that enhances traditional cribbage boards and takes advantage of cutting-edge 3D-printing capabilities. The board features standard 121 holes for a 2-or-4-person game of cribbage, but it excels with its unique ability to fold in half, serving as a protective case for the playing cards. This compact design allows the cribbage board, pegs, and playing cards to fit neatly into any pocket, purse, glove compartment, or other convenient location for an on-the-go game of cribbage! Another feature that sets the Compact Cribbage Companion apart is its advanced hinge design, which leverages the unique capabilities of 3D printers to print functional assemblies in a single print. The two sides of the board are printed together, requiring only a small amount of force after printing to break them free and enable the hinge to rotate smoothly. This innovative design would be impossible with traditional manufacturing methods, such as plastic injection molding, and it eliminates the need for assembly and prevents the board from ever coming apart. The Compact Cribbage Companion was printed on a RAISE3D N2 Printer using 1.75mm PLA filament. The critical aspect of the print is the hinge, where a layer height of 0.1mm was determined to be optimal through testing and research. This layer height allowed the hinge to break free and rotate smoothly after printing, making a finer resolution unnecessary and justifying the additional print time. A larger layer height, such as 0.2mm, could also work, but 0.1mm is preferred because it results in a smoother hinge assembly. The design can lay flat on the large 12x12” N2 print bed, but to comply with the 4.75x4.75x4.75” build volume constraint of this competition, a model that prints with the hinge half closed was created. This first orientation is named “Orientation 1,” and the half-closed model is named “Orientation 2.” Orientation 1 reduces print time and eliminates the need for support filament, but both models will print successfully. The prints take approximately 21.5 hours for Orientation 1 and 32.5 hours for Orientation 2. Because of these two orientations, the Compact Cribbage Companion can be printed on a variety of 3D printers with varying sizes and resolutions. The Compact Cribbage Companion was designed by Joe Jurss, a skilled Mechanical Engineering student at the Milwaukee School of Engineering (MSOE).
