This is the first 3D thing that I've ever made myself, I made it for when I get my Printrbot simple w/ the power tower & build area upgrade next year. I hope that others like it just as much as I do, I am quite pleased w/ the fact that I did this myself.
When printed out it can be smoothed out & painted to bring out the letters.
This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/cr46a9goPWw
Just set up & print as normal.
