I like that the model includes both a train and the environment. Great work with the use of 3D software and 3D printing is great, but I feel the research and sketching phase could have been stronger to further improve the concept. The thought process behind the model is solid, though. One thing I’d suggest is using less spray paint—while I understand the reasoning behind it, it might have been a bit much. I would have liked to see more interactive mechanisms, perhaps magnets or a string, to move the train, adding more functionality to the design

I really like that you're aware of the iterative process and are willing to improve your model. I also appreciate the level of research on functionality, interactivity, and form. I like that you tried working with magnets—great choice! Maybe try using lighter materials than 3D-printed components for the moving parts, and keep the 3D printing for the more robust areas of the project. Overall, great model and very clean. I love how well the model describes the project.

The flying tuk-tuk concept combines creativity, sustainability, and fun. The colorful clay prototype evokes a sense of adventure, while the central propeller adds an eco-friendly touch. The design addresses urban congestion with a solution that’s both practical and imaginative. While the prototype captures the look and feel of the idea, the lack of working mechanisms shows there’s room for improvement, ensuring form and function work together seamlessly in the future.

The form suggests a modular, stackable structure, which could work well with your intended mechanism, such as folding or expanding. Is the hole in the middle intended to represent a passage? If so, consider visually illustrating how objects or people might move through it. I think this is a strong start, and you could develop the concept further by connecting multiple pieces like this with a transparent tube to demonstrate the expansion and retraction of the system.

To improve the flying car design, focus on refining the shape for better aerodynamics with smooth curves and minimal edges. The prototype could benefit from incorporating more materials, such as transparent sheets for openings to give a clearer view of the interior, and different types of materials for the electrical components to enhance realism. Using a contrasting color for the moving parts would help highlight their functionality. Additionally, consider exploring alternative methods to connect cardboard pieces without relying too heavily on tape, which can detract from the design's overall quality. Nevertheless, it's a solid prototype to start with and a great foundation for further development.

Concept, sketching are well done. Prototyping could be better!

I really appreciate the simplicity of the design, and the attention to detail is clearly evident in the overall concept. The clean and well-thought-out shape gives the project a polished feel. However, I think the design could have been even more engaging with the inclusion of some movement or functionality within the car. It would have been interesting to see how mechanisms, such as doors, wheels, or other interactive elements, could have added more life and depth to the design. While the shape itself is appealing, adding these interactive features could have elevated the project by showcasing not only the visual appeal but also the car's versatility and innovative functionality.

Strengths  The prototype effectively uses cardboard, dowels, and simple mechanisms to represent the structure and functionality of the underwater train concept. Including a propeller element demonstrates an understanding of how propulsion might work for underwater vehicles, simulating movement through water. The train’s design incorporates a simple, streamlined shape, which aligns with the concept of minimizing drag underwater.

Suggestions for Improvement Incorporate wire or foam elements to create a more rounded, hydrodynamic frame Use translucent materials (e.g., plastic bottles) to simulate viewing windows, which could enhance user experience. Add LEDs for lighting elements to represent headlights or interior illumination.
