Why not use your square gears to make a spirograph type drawing set?

A video of my version, set of three gears:

For square gears and other mechanical goodies, a great online site is the Kinematic Models for Design Digital Library at Cornell University

Here's a movie of the one I made:

Thanks for sharing this Billion, it's awesome!

I wanna see these working :-)

Don't know if they're hard to make, but here a nice explanation of non-circular gears:

I hope there will be an entire family of these gears on thingiverse!

Would also be niced to see combo's of planetary gears.

Fantastic! I wanted to make some square gears a bit back, but got hung up on the math.

yes! i've been waiting for square gears =)
