Cochlear n7 processor file to look as realistic as possible so I can make hair clips for my daughter to share with family and friends to help stop her feeling out of place for having a cochlear Implant

I am looking for an experienced Freelancer to create a realistic 3D rendering of a cochlear n7 processor, with an STL file format, in a 1:1 scale size. I need someone I can trust to create a design that meets my expectations and creates a truly lifelike rendering of the processor for a meaningful memento I can share with my daughter's family and friends. With this creation by an experienced Freelancer, my daughter will be able to join in and feel like part of the group when everyone wears the clips.- has to be an stl file type ?
