Your gear's overall diameter will be roughly the outside_circle_pitch / 360 * number_of_teeth. Note that this will indirectly control the gear radius. This is one of the most important measurements, and is worth looking up more precisely.
outside_circular_pitch Roughly, this is the circumference of the gear. bore_diameter Size of hole in middle of gear. pressure_angle Part of the terms which, taken together, make up the gear tooth profile. cone_distance Important to the angle of your gear teeth. bevel_gear_pair() bevel_gear_pair (gear1_teeth = 41, gear2_teeth = 7, axis_angle = 90, outside_circular_pitch=1000) bevel_gear() bevel_gear (įinish = -1) Bevel Gear Finishing Options: NOTE regarding bevel gears: Two gears with the same cone distance, circular pitch (measured at the cone distance) and pressure angle will mesh.

When you want to update the submodule, do cd PATH git checkout master git pull. Then you need to do a git submodule update -init after cloning. If you host your project in git, you can do git submodule add URL PATH in your repo to import this library as a git submodule for easy usage. Since the maintainers aren't very responsive, may have to work around this somehow)
(There is a bug/feature that prevents including constants from files that "include" other files - see the openscad mailing list archives for more details. no top level code should create geometry). Some files include useful constants which will be available with include, which should be safe to use on all included files (ie. You can import these files in your scripts with use, where 'filename' is one of the files listed below like 'motors' or 'servos'. All the files are licensed under the LGPL 2.1 (see creativecommons dot org/licenses/LGPL/2.1/ or the included file lgpl-2.1.txt), some of them allow distribution under more permissive terms (as described in the files' comments). This library was created by various authors as named in the individual files' comments. It is currently unfinished and you can expect some API changes, however many things are already working. The MCAD library contains components commonly used in designing and making mockup mechanical designs.
