Breathe new life into old toys with this gear train!

The dovetailed rack gears are male, female, and male/female.

The design is a bit chunky so that little hands can easily grasp and manipulate this playset.

Now available on Shapeways! http://bit.ly/NapVP5



No assembly necessary. Just print and play.

The bores on the gears should be a snug fit on a 1cm shaft, but not so snug that a child can't easily attach and remove them.

A piece of sandpaper or masking tape will help adjust the bore and dovetails to the desired tightness.

The gears have 32, 16, and 8 teeth, respectively. Computing gear ratios is left as an exercise for the reader.

More pictures, please!!!!!!!!

I'd like to point out that the gears pictured will not move.

Flagrant stagecraft alert: pogden is correct.

That particular configuration is just for show, but the gears work fine if you arrange them properly.
