I wonder if you truly understand the term "printable". Are you trying for a real discussion
or did you forget to take your meds? You can "printout" diagrams, material lists and the
instructions needed to make many things, including a "stove", high tech or low tech:

Such material instructions have been available to all, using the contemporary media.
The rural community has always been more inclined to making use of such information,
than their urban counterparts. Still, many a crystal radio got built from instructions
printed on the cardboard that separated shredded wheat biscuits, in the city as well as
on the farm. Making anything in a city apartment can be a challenge, so some projects
are easier to accomplish, as a DIY effort, outside a urban environment. If that is what
you mean.
