 2) Install LeoCAD so you can find your parts (optional)
 3) Make a note of the .dat file name in LeoCAD, and then run:

-  unzip complete.zip
-  bin/dat2stl --file ldraw/parts/3894.dat --ldrawdir ./ldraw > 3894.stl

+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
+```
+bin/dat2stl --file /usr/share/ldraw/parts/3894.dat --ldrawdir ./ldraw --scale 4 > 3894.stl
+```
 
 For a 4X scale one of those!
