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.
- cardboard (single ply)
- laser cutter
- Autodesk Inventor
- 123D Make
- Elmer's Glue
- acrylic paint
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
9 sheets of 24'x18' cardboard
equalling a grand total of
(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!
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
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
