After some sketching, I realise that I can’t just design the whole assembly of the head wear altogether. There are too many moving parts so I need a reference to start with. I decided to start with the support structure that helps to whole device to rest on the head which also resembles the bridge structure of the conventional headphones.

I measured the optimal dimensions for 3D modelling before I start to 3D print it. I felt that with a physical form, it will be easier to build the entire head wear step by step, slowly adding parts and test if they fit together.

The two rectangular side slots are for motors that helps to open the ‘ear covers’ while the long hexagonal shapes are designed to hold future extension parts that will fit onto this model.

This is how to fit the motors into the model once I have some designs of the ear cover done.
