Please note this JS version of the tool currently cannot save in IE, but you can make as many cogs as your heart desires. To be able to save, please use the Non-JS dependant version

Cog layout 400 pixels pixels pixels pixels pixels radians radians radians
Optional extras

Leave as 0 for a solid cog, otherwise specify the width of the band the teeth are joined to in pixels. A value greater than half the inner circle size results in a solid cog.

Version 1.1

  • Added the ability to make the cog 'hollow'.

Version 1.0

  • Now entirely powered by JavaScript and Raphael (the JS library).
  • The cogs are live-previewed by SVG, and you can then click "save" to get a PNG version. Or you could just take the generated SVG code.
  • Added an Easter egg. Muahahaha.
  • The old Javascript-reduced version remains in place but isn't being actively developed.
