I made a semi-improvised process of designing a retro handheld console with DSLR camera aspects with a new CAD software Plasticity. I made the design by referencing a sketch I made but not sticking to it. I highly inspired from the DSLR cameras on this one. Because DSLR cameras have all the oldschool aspects by combining both the analog and the digital era. and also they have great physical UI with very usable buttons, switches and adjustment handles.
I also released a Plastic Finish Substance Material on my store which I used on this project for texturing. You can get it by this link:
