An initial product preview made in 3D in blender.

I need an initial product preview, like three different designs in 3D and an initial rendering. Specifications are loose, creativity is encouraged, no need for precision in measurements. We have some pictures of actual products as a basis for inspiration (we have more pics). A basic (cheap, not fancy) design is mandatory (but it can be beautiful if possible) then we also like two more designs targeting man and woman or unisex. A Button (and only one button) must be apparent in every design.
