In the early days of computer technology, there were computer games that did not use pixels but vectors. Asteroids by Atari from 1979 is well known. Lines were generated completely analog on a Braun tube (similar to an oscilloscope). This even allowed a 3D representation, but of course based on a reduced number of polygons. From this environment comes the meanwhile quite popular representation known as LowPolyMesh.
Such graphics can be implemented quite easily if you download a suitable 3D object (for example from Thingiverse) and simplify the meshes with Meshmixer.
Then you can use SketchUp's line renderer or Plotter Vision to create a vector graphic from it.
As with the city maps?, it may be useful to render some lines more boldly. With Illustrator, the easiest method is to convert the lines to areas with 'Object > Convert ...'. This way you get a double line.
For the actual conversion, it is a good idea to use the option of plotting white lines on black paper. After all, this is a graphical result that cannot be achieved easily with a classic printer.
