I have over 6 years experience in Art & Design and have developed a strong set of branding, sketching and modelling skills.
The job posted is easily achievable, as the method I work toward would include the use of 3D programs such as Maya and Rhino, which can then be converted into .stl files, before that however, I would research heavily into what you wanted from the product & discuss your needs from the product.
