What type of plastic were these gears made from? I was thinking about
pulling out one of my plotters, but I don't exactly remember where I put
it right now ;P

If they are made of nylon, I'm surprised that they split. I really expect
to find that they were made of some kind of ABS or ABS blended plastic
that didn't handle the press-fit pressure very well.

Has anyone contacted Alps to see if maybe they might know where the gears
were made originally? It's certainly possible a set of molds might still
be sitting around somewhere...
