Somebody would have to make one first. I didn't do it yet.

No. Worst case is that the rest of the mechanism degrades quickly.

Please don't get me wrong. I am sure you or Shapeways can print something that will somehow fit and turn and maybe even drive the other gears ;-) What I wouldn't like to risk is having it somehow work for some time, only to discover that more damage has been done to other parts due to inaccuracies (centering, teeth shapes, tooth walls smoothness, etc). And as we know - not only the directly adjacent gear can be affected.

Having said that - I am still very curious what would be the output. It is so small that maybe you can try just a quick shot of a generic gear that has the (I don't know the English terms for the gear parameters) outer diameter of 3.7mm and 1.5xx (don't remember exactly - maybe somebody can check it directly with his device) inner hole. There should be some generic designs with appropriate number of teeth that one could resize. Not to work with this one later but just to have a kind of POC if spending time on exact reversing the actual gear makes sense as of now.
