this explains it best: https://en.wikipedia.org/wiki/Modular_design
can you put the whole shop in a box, if there was a sprinkling of
incredible kickstarter gadgets, and a fabrication guide based on assembly
from existing appliances and hardware ?
most engineers always start from scratch, this costs a fortune.
like programming, you want certain systems, repeatable quickly.
plus, you are not here to make anything, only answer the needs
in ones community. all the rest are miniscule in need to me modularizable.
