I am Fuly Obel, a professional with extensive experience in the fields of architecture and engineering. I specialize in project execution, architectural design, projection and digitalization of plans in different disciplines (such as civil, mechanical, electrical), metric calculations, 3D modeling, photorealism and rendering.
I understand from your description that you are looking for a professional who can take your autocad 2d image of a bin design and create a 3D model and working animation in .STL format. Additionally, while you have approximate dimensions for the bin design you are open to creative interpretation when it comes to any features or mechanisms in the animation that may be required. My skillset includes taking on complex projects such as this one.
I'm confident that my expertise in 3D Modelling, 3D Rendering and AutoCAD would be the best fit for this project. With my expertise in these areas I am able to produce high quality models and animations tailored to client needs as well as cost effective solutions for any given project.
