Alrighty... so this Instructable is a test to one's patience and
perseverance. For my father's birthday I decided to make him
a Turner's cube, however, I decided not to make it the
conventional way. Instead of using a lathe, my choice method
for this project was to 3D print the cube (or cubes) by way of
the laser cutters at TechShop San Jose.
Yes... I am a little bit crazy....
The main reason for my choosing this method was the fact
that I have a lot of cardboard hoarded up at my house, and
needed to use them for something.

Things used:
  • cardboard (single ply)
  • laser cutter
  • Autodesk Inventor
  • 123D Make
  • Elmer's Glue
  • acrylic paint
  • polyurethane
  • Step 1: Design It!

    First I started off by making a 3D model using Autodesk Inventor.
    Draw up a few cubes, extrude some holes through each face,
    and do a sphere cut out of the inner surfaces.

    Then export a .stl file.

    Step 2: Slice It!

    Next, using 123D Make, I imported my "turner's cube".stl file
    and typed in the dimensions of my cardboard to create
    the slicing files for the laser cutter.

    Step 3: LASER it!

    Using the vector files from 123D Make I cut out all of my
    slices.

    140 layers
    9 sheets of 24'x18' cardboard
    equalling a grand total of
    904 pieces
    (didn't I say I was a bit crazy muahahaha)

    since there were so many pieces, and a lot of them in the tiny
    size range, I decided to use a piece of sacrificial material
    underneath my cardboard to help take all the pieces out of
    the laser bed.
    (after 9 layers of cutting, I got a pretty cool [accidental art] piece
    out of my mdf sac layer and my cardboard scraps,
    one of these will become an Instructable as well in the near
    future, wink wink ;)

    Step 4: Assemble It!!!!!!!!!!!!!!

    Ya this this step deserves all those exclamation marks.
    As usual, this is a pretty self-explanatory step.
    Using Elmer's Glue I glued together all 904 pieces.
    The smallest cube I glued all together, and the larger cubes
    I kept in two halves until they were all painted and ready to
    put the smaller cubes inside.

    Step 5: Paint 'em!

    Using acrylic paint I painted the cubes
    white, light blue, and blue. =)

    Step 6: Cover it more Plastic!

    And then....
    I painted on a few more layers of polyurethane for a
    glossy finish and little bit of strength.

    Step 7: Glue the Big Cubes together

    And the final step,
    place the smaller cubes inside the larger and glue together.

    voila 7 inch 3D Printer's (Turner's) Cube!


    a suggestion for those who wish to make their own:
  • i would highly advise extruding a cylinder through the four corners of the original model. that way all the pieces have a hole cut out and you can use that to align them with a steel rod or wooden dowel. Gives you added strength and saves you the headache while gluing everything together. win win =D
