 These models are all very nice, but we need have a nice file, normally dxf to use in a laser-cutter. So we can do this automatically.
 ```
-/bin/bash ./convert-2d.sh examples.scad 
+./convert-2d.sh example.scad 
 ```
-This generates three files; 
-* examples.scad.csg  
-* [2d_examples.scad](https://raw.githubusercontent.com/bmsleight/lasercut/master/2d_examples.scad)  
-* 2d_examples.scad.dxf
+This generates following files (depending to SCAD source filename); 
+* example-flat.scad
+* example/
+  * example.csg
+  * example.dxf

-To adjust the positions of the cut-out, so that are not all along the y-axis the parameter flat_adjust can be used, either in the main files or tweaked in the 2d_ file. For example flat_adjust = [110, -350]), would put the next peice at 110 in x direction and -250 in y-direction. With just using flat_adjust four times, we get a more practical example.

+## Files for 3d printing (or limited use with cnc depending of used endmill)

+If you need a version for 3d printing you can comment out a line of the YOUR_FILENAME-flat.scad file and exported a stl file.
