Hi, I can help turn your prototype into a proper mechanical CAD assembly with a working grabber mechanism and storage section. I’ve worked on prototype-style projects with moving mechanisms and 3D printed assemblies before, including a smart building prototype with a vibration-triggered geared motor mechanism and custom printed parts, so I’m comfortable working on functional concepts and iterative improvements. I can work from your sketches, dimensions, and handmade prototype to refine the design into a clean and practical assembly for prototyping and future production. I also want to be transparent that I’m still building my profile on Freelancer, so I kept my bid lower while building reviews and long-term clients. Looking forward to seeing the concept.
