glChess chess set 2

This is a version of the chess set from glChess and the Linux xscreensaver hack called "endgame", which I first posted as Thing number 322616. That version had severe overhangs that could cause problems with all but the very best slicer software. This version changes all overhangs to less than 45 degrees, making the set more likely to slice and print without difficulty. The sole exception to the overhang rule is the knight, for which a manually-generated support has been designed. If you wish to try auto-generated support for the knight, the version without the support structure is also included. All pieces have been scaled correctly for a standard chess board size (that is, 25% larger than the original set posted).
Update May 20, 2014: The knight support structure was modified to reduce the gap between the support and the piece.
