Large Stencil

I needed to make a stencil that was larger (about 14" x 11.25" or 355mm x 286mm) than our 3D printer. And I wanted the stencil to be plastic, not hand cut paper or cardstock. (Once again the NEED of a laser cutter pops up) By dovetailing or puzzle piecing the parts together I could make any size stencil I might need.
With this method I could also change out just part of the stencil. For example, change out a name or date from within a stencil of text without having to reprint all of it.
