Classic Chess Set from glChess Free 3D print model

This is the chess set that is used in the xscreensaver program "endgame" and others on linux systems, itself taken from an older program called "glChess". The xscreensaver programs are all open-source, so the modeling data only needed to be recast from OpenGL calls to an STL format, written to files.
Because it seems that nobody can make a proper knight, I redrew the knight as "classic_knight_3". This is not part of glChess, but makes a better set, in my opinion.
