Stop Sign

Want to learn OpenSCAD and I need a couple of stop signs. I plan on also learning how to do filament switches and print this with red base and white top. Or if I'm lazy print red and paint the raised border and text white.

Included the scad file.

##### Why isn't it customizable?
Because of the font and the formulas I use it's not worth making customizable. I tried. But for a stop sign you need a narrow (tall) font. Looks like the one I picked isn't available here.

##### Specs
Based on https://en.wikipedia.org/wiki/Stop_sign#Specifications
Width = 750mm (100%)
Border = 20mm (2.7%)
Text Heigth = 250mm (33%)

And simply scaled it down.
