I... so.. want... a 3D printer... drooling since the first
   articles came out.
   Back in dot matrix days I drew up plans for a 3D printer.

   The idea was, the dots would use a much thicker ink and the
   platen would back up as it passed over the same spot over and
   over again in increments the size of the dot.

   Waited a long time for someone to actually make something -
   didn't expect them to use an X-Y PLOTTER for the base design but
   it makes sense over a roller.

   Just too lazy to build, too cheap to buy.
