**6mm Now Availabe!**

Use spragg6-6mm.stl -- the model has been scaled up 133% to fit 6mm bearings, but the hex hole remains 1/4".

**0.3 Now Available!**

This ratchet uses several 4.5mm airgun BB's instead of plastic catches to make it stronger. It turns freely forward, and locks solid backwards, see the video. It has a 1/4" hex in the axle for screwdriver bits. You could also use it as an overrunning clutch.

I modified it from my ratchet v0.1 by making appropriately large holes in the housing for a 4.5mm BB, deepening the channels, and letting the axle fit the housing freely. The results were beyond expectation -- it's both free-spinning and strong enough to turn screws!

[edit] Stronger six-ball version available in spragg6.stl. The case is also slightly different to accomodate it.
