Corrugated_Sign_Modified_V4.0

MathGrrl built the original model for the Corrugated Sign - her summary follows:

A large sign that prints in a tiny footprint, fully assembled, with no supports.
Use the Customizer to type in your own word or phrase. You can also use this model for secret messages that are only visible after printing, because it is not possible to read the sign in its folded STL format.
Future plans might include font options, styling, and speeding up the code.
