FreeSans Block Typeset Font Free 3D print model

This is a basic character set built from the "FreeSans" font created by the FreeFont project (see http://www.gnu.org/software/freefont). I have had difficulty using the Wings3D "Text" function, because it only generates text that is free-standing in air. So I created a set of characters each in its own block, like typesetting blocks used for pinting presses. The set of files includes Wings3D and STL files of both extruded and intruded characters.

Updated on 4/1/2014 to remove errors in edge orthogonality apparently due to roundoff error in one of the tools.
