With my experience in 3D design, particularly in the industries of gaming, film, and virtual reality, I have developed an eye for creating captivating yet functional models that I believe will benefit your project immensely. One of my specialties is optimizing models to ensure ease in transitioning between different sizes and materials such as PLA or ABS. Combining this skill with my proficiency in Blender and other industry-standard software, I can expertly modify the joint holder model to hold 6 joints comfortably while adhering to the desired sleekness of its design.
Moreover, as a passionate designer who always strives for excellence, I understand the importance of maintaining visual appeal while maximizing functionality. For your joint holder project, I assure you an updated model that remains convenient to use with a tethered lid but still compact enough for practical portability. Additionally, I assure you that the final deliverables would abide by the scaled version requirement and include variants suitable for printing with or without image additions.
Lastly, I would like to mention that although my previous work primarily revolved around high-end projects such as games or films, I am extremely adaptable and able to translate my skills effectively into smaller-scale projects such as yours. This makes me best suited to take on your micro project and tailor my designs specifically to your requirements.
