Before I commenced shaping the final appearance model, I started spraying this second model with foam and shaping this. This model will show the development of the product from the first test rig model to the final appearance model. I have formed the foam across the whole model. All that remains is to attach the trimmer body section to the model and this will be complete. The aim of this model was to concentrate on the ergonomics and fit of the top section. This was to test how the product would feel when used. This, along with feedback, informed me on what the final shape of the final appearance model should be.
