I recently created some product displays mock-ups. Industrial design isn't one of my specialties, but after some research, I found it was not difficult to find inspiration and get things going. I wouldn't consider these production templates by any means, but they should give the factories and our clients a good idea of what we are visualizing.
I decided to build these in Adobe Illustrator, utilizing the 3D grid. From there I approached the sample items as if building illustrated icons, using opacities, simple shapes, and clipping masks.
