I used some boolean modifiers to create this Object. Added a caution sign, some rough looking materials that look rusted and aged. I created a greeble floor on some of the scenes and changed the front to a emission shader to look more Sci-fi. I also uploaded in a toon shader. I would love for someone to leave me a comment. I learn more if you have suggestions. Thank you.
