This is my second attempt which I named as "Inside Out Modeling". First one was Quickjoy Joystick Project which is found here:
This time I modeled my good old Commodore 64 by CAD modeling technique, and painted it with PBR texturing.
I model this kind of plastic/electronic devices by disassembling and taking measures with calipers for maximum resemblance. Then I do UV work in Modo and paint them with Substance Painter.
I uploaded videos of whole bunch of modeling and texture painting timelapses of this piece.
Hope you like it.
