Figure 5.2 The STL file as viewed in Repetier.
This object is a small, thin, rectangular plate (with rounded ends) that has the
words “Hello World” created via holes in the solid object's body. Right now, I'm
not concerned about all the buttons and values being displayed in Repetier. In-
stead, I want to open up the STL file and confirm that I can view it in the 3D View-
er. (Click the 3D View button if you don't see your STL file after double-clicking
it.)
