Also note, this assumes no botched parts... If you botch a print, then you
will need to re-print that part. Which can cost a lot of plastic (since the
longer the print, the higher the chance of blowing it, so the largest parts
are the most likely to botch). That said you could print the whole set
without screwing a single part up if your printer is tuned well and working
well. Just pointing this out.
