Sorry to bring this thread back from the dead, but the news is good.
A short while ago, I bought a 3D printer and eventually got around to designing a replacement for the missing gear. On the 7th attempt, I have produced a gear that works perfectly.
Will it last? I'm not sure. But a temporary gear is better than no gear at all.
If it is anything like other gears I have made for other locos then it should be fine.
Why apologize? Nice to see a self-reliant solution to the problem. Okay, it has taken quite a while, but you've done it, and if you've kept the design on file you can presumably print more gears at will, should it wear out or fail.
