This was intended to be a customizer project but due to the fact that the customizer cannot use libraries, I can only describe how to customize this.
1) Download all .scad files and save them in the same directory.
2) Download and install OpenSCAD if you do not have it already
3) Open "Customizable Name-Block.scad" and edit lines 5 and 8 to read your name or any other two words
4) Press F6 (or Render)
Press the STL button on the top toolbar to create and save and STL file.
