Customizable Jigsaw cutter

Now with customizer for easier scaling and printing. Set the width and size to suit your printbed.

This jigsaw made in **Inkscape** using my extension here:
- https://github.com/Neon22/inkscape-jigsaw
- Requires Inkscape 0.91

Then exported in V7 of DanNewman's **Inkscape to OpenSCAD converter** here:
- http://www.thingiverse.com/thing:25036

And then edited to make one side of the jigsaw cutter sharp.

You can make Jigsaw's of arbitrary size and shape by using the inkscape extension and a bit of manual editing. (Use the example scad as a guide) :)

Takes a while to F6...

Saw Spina's [jigsaw](http://www.thingiverse.com/thing:245080) and made one in OpenSCAD with my Inkscape extension - originally designed for laser cutters.
