This is a library of small, matching gears intended for 3D ABS extrusion printing, I use these to make my own gear boxes.
I needed gears for some of my projects and eventually wound up creating this set, which I've dubbed "Gear Set 1", and created a reference chart to aid in the pairing of its gears.


These gears are scaled to the smallest size I could print while still getting something that actually worked. To pair the gears up please refer to the attached PDF for the necessary dimensions.

If you would like further details check out the accompanying instructable for all the sweet details you can handle:

Hey In the foreground of the 3rd photo is some gears mounted to a sort of u brace. do u have the file for that mechanism? working on a small ornithopter project and I keep seeing that gear mount but cant find the file anywhere!

That brace was just for experimenting / proof of concept and I can't find the file now. However, I also played around with making some prototype ornithopters and you can find those files here:

I also documented my process in an instructable:

Good luck with your project and remember that the lighter, the better! I kinda abbandoned my project but I plan on revisiting it someday. After watching some documentaries on how animals fly I think that the main problem with my version of the ornithopter was that the wings didn't bend right and so they created as much force pushing up as the did pushing down. The next version will try to emulate how bats fly.

also, i realize I had already been using your Instructables page as a reference, small world haha!

do you know what gear u used to drive the bigger gear? didn't see that in the file you linked me too, just curious.

Yep, it is the 8 tooth gear, I added the one used in the ornithopter to its project page and the instructable.

thank you so much! it's a super fun little project. thanks for the tips too. I will let you know how the project goes!

Love the gear set I work with model train stuff any you have inspired me to do more animated decorations on our club layout

Oh man, that gets me immediately thinking about automated bridges and crossing arms, sounds like a lot of fun.
