I am working on a project and I need help editing the 3D CAD of a human skull. I already have the 3D CAD designed, however I need it to be hollowed out more. This reworking of the 3D CAD will require an engineering perspective, because I need the eye cavities of the skull hollowed out to spec. I also need the cranium of the skull to be hollow, so I can thread wires through the eyes, and then up through a hole in the top of the head. If you're looking at the skull from the side, the wire threading should look like the capital-letter "L" rotated rotated 90 degrees to the left (see photo attached). I am looking for help in editing my 3D CAD, and I need it to be extremely precise. This is a time sensitive matter, and is a product that is currently in production as a motorcycle accessory. Please reach out if you can help. I only see this being a 4 hour job; this should not take more than a half day. The 3D CAD file is a bit large, and will not allow me to attach to this job posting.
1. Hollow out eye cavities with a slight recess inside, so a lip of an LED wedge can snap into place in the eye cavity, and be secured
2. Thin out the wall thickness of the cranium of the skull
3. Rework the CAD, so that the bracket of the motorcycle sits flush in the top of the head
4. Thin the thread holes for the screws, and make the holes deeper... this will simplify the work for the machinist... they only need to widen the holes and then thread the holes.
