Woodworker Matt Wandel has a tool on his site for designing your own “low precision” gears (i.e. wood, phenolic plastic, etc) and printing them out onto paper templates for cutting. You can define two gears (with tooth size, count, angle) and watch them interact. The site also includes a brief tutorial on how to cut out the gears from the templates.

    SDP-SI has downloadable DXF format CAD files of various spur gears. I’ve used these in the past to make custom gears.
