Parametric No Soliciting sign

There are a number of existing No Soliciting signs on Printables, including this one which I drew inspiration from, but I opted to create my own in OpenSCAD in order to support different sizes and more colors.

The included .3mf files are for 7" and 3" signs. You can use OpenSCAD to select a different size and further tune the model as needed.

I printed in PLA with .2mm layers, with color changes at 1.8mm and 2.8mm for the border and text, respectively. I also enabled ironing on all top surfaces.
