Stencil

This is a stencil my neighbor asked about. I had printed raised letters in Sketchup, but cutouts were always evil. New strategy made it slick.
A flat rectangle and the 3D text tool. The catch was that I set the 3D text tool to not filled and not extruded. Placed it on the rectangle and scaled it just the way I wanted. Selected them both and used intersect faces.
I then drew connections for O's and such or added a small piece to keep the center of the letter in place.
