BB Ratchet 0.1

**0.2 is much better than 0.1, see http://www.thingiverse.com/thing:207389**

I got sick of printing xmas things and decided to have another crack at what I actually got a makerbot for -- making machines.

I saw a diagram for a ratchet using BB's and springs which caught my interest, as it looks MUCH tougher than an all-plastic ratchet would be. The plastic spring part can be thick and tough, and doesn't need to move far at all. And the holding force doesn't get concentrated on the weak tip.

You know the drill by now. This is an experiment, not a practical part -- even though I'm happy to say it works -- and if you want to use it yourself, get the OpenSCAD file and fiddle until happy.
