Due to the strong popular demand by a single person I wrote a generator for a traffic light housing that will be used for a Jenkins monitor. Here the prototype which already looks correct but still had issues with the fingers of the front panels overlapping in the horizontal walls:

The generator also creates circles for cutting out the "glasses" for the lights but I didn't want to spend the material just for trying out the generator.
