Open-Source Papercraft, or, a box for your cell phone!
Here, step-by-step, is how to get a box for your cell phone, Ipad, whatever, using only
Open Source Software on Linux.
There are Windows versions for
all these programs.
Begin by designing a box in Wings3D, a box with windows, don't use inserts on a face, but rather a face cut into 3, because it works out much better, I'll explain why, later on;
Now, export the box on the Obj format, and import for MeshLab so that you
can save the file to Dxf, save it in the sub-folder "Examples" folder of
the Dxf2Papercraft. That way the 3D Dxf files are on "Examples", but the 2D Dxf files are not!
With the Dxf file in, go to... The Dxf2papercraft Program,
which, with a line of text that is always the same, just the
file names change, you may turn a 3D Solid, into a 2D sheet to cut and paste!
And with 5 different ways to do so, see the Help text that shows up on the Terminal.
Remember first, enter the folder where the Dxf2papercraft is, in this case a folder on the Desktop, so write
And then just input
./dxf2papercraft_32bit examples/telele3.dxf telelesheet3.dxf
Thus, the name changes, into the name you gave, plus "sheet," blahblahblah turns into blahblahblahsheet, for sheet as in, 2D.
Inset faces as windows do not work well on this Program, it is better to cut a face in 3, and delete the face in the middle.
Then import to LibreOffice 3.5 Writer, which you will export to SVG:
Yes, set somewhat awkwardly, but it is child's play to straighten up the drawing in Inkscape:
It is important to make the bending clear, and precise, nothing simpler than the method of the slot between two rulers, here's a Meccano version:
It is a rounded piece that passes over the sheet, on the groove between the rulers , and a you get a clear crease:
And by cutting and pasting, or riveting on plastic sheet, a piece of aluminum sheet, to protect the body and boost the signal, for you want the signal to focus on the cell phone, a lining of cardboard and a thick acetate window, you get this:
Not bad for a 70 cents plastic sheet, and 15 minutes of work!
