The prompt
Interchangeable Hair System: The character should also have removable/interchangeable hair. My current concept uses two small, shallow attachment dents/holes on the head, with matching attachment points located inside the removable hair piece. I do not want large holes to be visible when the hair is removed. The hair should stay securely aligned when attached but still be reasonably easy for the user to remove and replace. The two-point attachment system is only my initial idea. I am completely open to the designer tweaking, improving, or redesigning the hair attachment mechanism based on their professional experience. If another mechanism would be stronger, smoother, easier to manufacture, or better for repeated swapping, I would like to hear their recommendations. The important goals are that the hair attachment is secure, durable, easy to swap, visually clean, and suitable for future manufacturing. Prototype & Deliverables: For this first stage, I am looking for a functional prototype design, not necessarily the final mass-production design. I want to be able to 3D print the figure, physically test the articulation and interchangeable parts, identify problems, and make revisions afterward. I would like the final deliverables for this stage to include the 3D-printable files as well as the editable/source CAD files, so the design can continue to be developed later. I already have a concept/reference sheet showing the approximate proportions, dimensions, articulation points, face mechanism, and hair attachment concept.
