Summary
This is an update to http://www.thingiverse.com/thing:3575 (V5.0) adding the ability to flatten a gear (make it 2D) allowing it to be exported in DXF format ready laser cutting.
Instructions
To flatten a gear just add the argument 'flat = true' to the 'gear' module call and you will have a nice 2D gear ready for export :-).
gear(flat = true, [normal arguments, ...]);
TIP: See openscad example017.scad (File>Examples in openscad) for a good example of a model, which has extra code to allow exporting for construction.
