ldraw2stl

Convert LEGO LDraw files to STL, for super-sizing and 3d printing!!

Locate the ldraw parts archive at getting started (note: the wget link below might go stale):
Install LeoCAD so you can find your parts (optional)
Make a note of the .dat file name in LeoCAD, and then run:

wget https://library.ldraw.org/library/updates/complete.zip unzip complete.zip bin/dat2stl --file ldraw/parts/3894.dat --ldrawdir ./ldraw > 3894.stl

Use the --scale argument to scale the part:

bin/dat2stl --file /usr/share/ldraw/parts/3894.dat --ldrawdir ./ldraw --scale 4 > 3894.stl

For a 4X scale one of those!
