Hi All,  I have a web site named http://playerpianorestorations.com that
I'd be happy to use as a "Library of Printable Parts".  I've been thinking
that the day isn't too far off when a fair number of the parts we use
in restoring player piano mechanisms will be cost-effectively made on
a 3D printer.  The costs have come down significantly in the last two
years, and I see that trend continuing.

Musically,
