Open Example File
Let's start with printing a classic 4x2 LEGO brick. Open the file examples/classic/brick-4x2.scad with OpenSCAD. You should see the following:
Render and Export
Before we can export the model as STL file we need to render the scene. Press F6 or click Design -> Render in the menu.
Depending on your computer this can take a while.
Now that we have rendered the scene, we can export the model as STL file by pressing F7 or clicking File -> Export -> Export as STL ... in the menu.
