In today's session, we had the opportunity to print the various prototypes prepared for the final presentation. This marks a significant milestone as we approach the culmination of our project. We printed two prototypes designed for fork use and two prototypes designed for knife use, reflecting our commitment to versatility and meeting diverse user needs.

For the measurements, we used one knife and one fork from IKEA for two of the prototypes. These utensils were chosen due to their wide availability and standardized dimensions, ensuring that our designs can be easily replicated and used with commonly available items. For the other two prototypes, we used the dimensions of commercial cutlery from the campus kitchen, which provided a different set of measurements and allowed us to test the adaptability of our designs with various utensils.

Taking the measurements from www.ikea.com in the kitchen utensils section as a reference, we scaled the following photo using the CREO Parametric software. As engineers, we often do not find the complete measurements of certain products, so features like these offered by parametric 3D modeling programs are essential for designing our products correctly and more easily. Thus, we scaled the photo to determine measurements such as the width and height of the knife or fork, allowing us to modify our CAD to adapt to these dimensions.

As we prepare for the final presentation in the next session, we are compiling all the data and feedback we have gathered throughout the project. This includes user feedback from Diego, insights gained from our various prototypes, and the technical details of our design process. We are excited to present our work and demonstrate the practical applications of our prototypes. We believe our efforts will significantly impact users like Diego, enhancing their independence and quality of life.
