This is a kind of implant shaping machine called ‘Sirona Cerec’.
Even if I am not modeler, I think I am getting familiar with hard surface modeling.
Work period was required a week for modeling. Then, it took additional 3 days for UV ,texture, and rendering. Therefore, total 10 days were taken.
Inserted spline IK and bound skin both copied joints and curve.
Now, I am rigging this machine. I will upload a scene how this rig works next time.
I updated new article. You can check it from next link here.
