About this 3D model

Based on srepmub's OpenSCAD train track library, with a few additions. I can now make pretty much any track layout I can imagine! This is pretty much why I bought a 3D printer. :-) Changes: 1) Improved SCAD file readability (renamed methods & variables) 2) Added some new tracks (triple track, double curve) 3) Added smaller radius turns (curved and straight track small) 4) Works with connector thing http://www.thingiverse.com/thing:15165
