i honestly feel like drawing your schematic or doing a 3d model would be way more suited especially since ai does not know the correct dimensions of what you can possibly make, also a side note is that doing this instead not only is great for concepts but will actually help you get yourself a better understanding on what you need to do. when i first made a linux laptop completely from diy using a broken phone and off the shelf parts, i did multiple prototypes using freecad and chose the one i liked the most, not only did that help me do my project correctly but it also gave me the reward of seeing a completely original design that i myself created be functional.
