Basic introduction to gears and gear ratios. This set of gears, crank, expandable base, and several spinners can be used to demonstrate the anatomy of a gear, how gears mesh, and visualize different gear ratios.

Print:
1 (or more) 11-hole base
2 (or more) feet [standard or expansion]
1 (or more) of each gear
1 crank
1(or more) spinner

Special thanks to b2vn (and Randall Munroe!) for the excellent xkcd character models. For more nerd fun, go to: https://xkcd.com/

**UPDATE 9/25**
- Added expansion foot - this will allow you to connect as many bases as you'd like for even more gear fun! (Note: expansion feet won't interfere with each other, so go nuts.)
- Added more spinners, including an arrow to help demonstrate rotation/counter rotation of gears.
- Updated crank
