I want to print some gears, but I dont know how to make them Answered

So I'd really like to make some geared mechanisms to be printed out, but the math is a little bit beyond me. Right now I have 123D and it does not have a gear generator. I was thinking that somewhere there has to exist a catalog or database of pre-designed gear stl files.

I was hoping that somebody here might know of such a thing, or perhaps another way to easily make gears?

I've been seeing all kinds of crazy gears made into really exotic shapes, but I don't know how these are made either. I'm assuming that the people that designed them are super geniuses, or that they have some kind of advanced software. Which is it?

Might check out: http://joostn.github.com/OpenJsCad/

Found that and haven't had to worry about gears since.

Here's a helpful youtube video showing how to make gears in Corel Draw

Also if you're going to be cutting gears check out a laser. I used a hobby laser from Full Spectrum Laser to cut the gears in the image. They just released a new hobby laser on kickstarter here: http://www.kickstarter.com/projects/fsl/affordable-20x12-laser-cutter-engraver-assembled-i

Thanks Hawkster, that did help :D
I actually found a few ways to do this and I figure I might as well share em:

1. Use Inkscape to draw the gears and import them into 123D. This is the wonderfully detailed tutorial that I came across from Make http://blog.makezine.com/2010/06/28/make-your-own-gears/

2. Use the gear template generator and save as a pdf. Open that pdf in illustrator (inkscape too probably, but I didn't try) and save as a dwg. That file can then be imported to 123D.

What I didn't find was info on how people are designing these crazy gear box things. Anyone have any ideas?

That looks like a very complicated drawing! I am glad to know that the information helped you.
