This is an unofficial repository to hold all of the models from LDraw in both their native .DAT format as well as in the .STL format for easier manipulation and 3D printing.
.DAT files are stored in the ldraw directory (it's a mirror of LDraw's part library), specifically in ldraw/parts. .STL files are stored in the stl folder. The dimensions of each part are also stored as .JSON files in the dimensions directory.
A list of all part names can be found in the partsList file. This will be their file names in each folder (of course, with a file extension added).
The repository can be updated by running updateLibrary.sh in the scripts directory. This will load any updates from LDraw's website and update data in the library accordingly.
