3D Design 3: Original Design and Print
The goal of this assignment is to demonstrate you are able to think 3-Dimensionally and design something that requires a combination of shapes, with specific measurements, which overlap, fit inside each other, nest, pivot, or connect. To achieve this you can choose one of the following options:
Glow Circuit - Your own version that lights up. There are two approaches. Review your options and techniques below.
Complex Design (hinge, fitted parts, modular, precise measurements)
Themed chess pieces (3-5)
TinkerCad Tips: Be sure to explore the additional featured shapes offered by the community on the right drop-down menu. There are a ton of options that you can alter the properties of to get unique shapes.
FabLab 102 Extensions:
3D Print 4 - Design a circuit bracket that holds an CR2032 battery, switch, LED or motor.

Do some quick concept sketches - Consider overhang areas and minimize detail
Play with the shapes and TinkerCad Community shapes (right side drop-down menu)
You can make one of the following types of Glow circuits:
A. Window: Use the window technique to create holes for the light to shine through. Examples: windows, eys, or slits
B. Glow: Make a design that is hollow and has a thin wall which allows light to illuminate through. There is a special strategy for printing this hollow design. Ask for help.
2. Complex Parts: The intent of this option is to demonstrate a strong understanding of precise measurement and interconnected design. This is observed by creating parts that either hinge, fit into each other, connect, detach, pivot or move. This can be a fix for a part, a nested box, a bracket to hold an item, etc.
Share your idea and some quick concept sketches with your teacher.
Think through which parts are moveable and understand fit tolerances.
Fit Tolerances for Interlocking Parts - For objects with multiple interlocking parts, design in your fit tolerance. Getting tolerances correct can be difficult. Kacie’s tips for creating correct tolerances: use a 0.2mm offset for tight fit (press fit parts, connecters) and use a 0.4mm offset for lose fit (hinges, box lids). You will have to test it yourself with your particular model to determine what is the right tolerance for the thing you are creating.
3. Pay close attention to overhang, bridging, and support
3. Themed chess pieces (3-5)
Make a set of chess pieces that look like a unified design. To achieve this, have common shapes and size for the base of each piece.
You should design an entire set but only need to print a minimum of three pieces.
Print one piece first to check for size and design. Once you have approval you can print more pieces.
