Make it yours

This recipe describes a treatment rather than a thing. Put your own subject in and it is added to the end of the prompt.

Prompt

Industrial concept art halfway between a drawing and a render: the machine painted in clean flat colour with soft shading, and loose construction lines, section marks and cable routing drawn over the top in thin ink. Plain grey background with a few stray guide lines running off the edge of the sheet. Confident designer's hand, no lettering or annotation text anywhere. Subject: a small racing kart with exposed cables.
