 ====== Overview ======
-Gears are one of those mechanical devices that everybody knows how they work, but until you need to incorporate on into your next project, you usually don't know the details behind all the theory of gear design. Gears are a fundamental simple machine that provide mechanical advantage, trading rotational speed for rotational force (or "torque").

+====Parametric Involute Bevel and Spur Gears====
+[[http://www.thingiverse.com/thing:3575|http://www.thingiverse.com/thing:3575]] is a script for [[http://www.openscad.org/|OpenSCAD]] that lets you have a lot of control over how Gears are created.
+This option does not have GUI, but requires a little familiarity with OpenSCAD scripts. Another advantage is that this script can make 3D gear models suitable for 3D printing. Most of the other options generate a 2D design, that you can directly laser cut, or edit in a CAD program to extrude a 2D shape for 3D printing.

+====Inkscape====
+Inkscape [[https://inkscape.org/en/|https://inkscape.org/en/]]
+Is a vector-drawing program that ships with a basic gear generation extension built in. Given that Inkscape is more "Art-centric" than mechanical design, it's use is good for a stating point, but you'll often have to import the result into another editor to tweak the resulting model.
+===== Honorable mention =====
 If your gear is purely cosmetic in nature, or what you need is a sprocket for driving a chain, check out [[http://www.idleamusements.com/?page_id=54 | Sprocketeer 2]] (Free, Windows Application, Web Application)
+If you're an OpenSCAD fan (and if not, you should be) There is also a nice list collection of gear, screw, and pulley creation scripts [[http://www.thingiverse.com/akaziuna/collections/openscad-gear-scripts/page:1|here]] (We have not tested most of these at Anibit, so use at your own risk).
