After drawings, it is time to make some box in styro, to better feel the shape and how it will fit in hands. I made several trials. It's not easy to find the perfect balance betweeb size, shape, sexy look, good ergonomy, light weight, etc... The prototype will not be perfect for sure, but it will benefit to check the dimensions, size, and ergonomy. Let's hope it will work like that, it would be nice to keep the box small if possible.
