        Are you supposed to customize the letter plate in your slicer before
        printing?  The default plates in the zipfile don't seem well designed
        for a traditional movable type system.    It's 13 full copies of the
        alphabet, and 3 lines of the most common characters, but even that
        leaves you with an abundance of X, Z, K, etc... and a relatively modest
        number of vowels.  There doesn't appear to be any capital letters
        I'm also confused as to the purpose of the "plates stl" directory that
        has many seemingly very similar blank plates.  The "how to make plates"
        documentation is all about building custom graphical plates.
        Amusingly, my slicer is estimating that it would take 28 hours to print
        the letters and spacers.

          3d printing an entire custom graphical plate with text already on it
          seems more practical in production terms, although of course you
          would be limited in design terms by the resolution of what you could
          get out of your printer.
          It would be interesting to do 4-color printing on this as well -
          obviously you would not have fine enough resolution to do a true
          "screen" but you could do what amount to multicolor woodcuts.  
          Wonder how good the "reproducibility" is, in terms of ensuring that
          the paper is always accurately aligned/etc.  Part of the charm
          though, I suppose.
          Perhaps you could do the block-printing equivalent of "ascii art" and
          use some pre-printed blocksets which don't correspond to actual
          characters, but which could be arranged to print some approximation
          of an image.
          Or just ascii art itself although these blocks appear to be fairly
          big for that.
          Pretty neat and fun little idea.
