Airport Runway Tiles Modified For GreeblyCity

cults3d

This is a modification of the GreebleCity Set7 Airport. The original runway tiles had heading markers "12", "24", and "48". Unless this is a reference I don't get, these numbers are wrong. They are the heading (compass direction) of the runway in 10 degrees, e.g. a north bound runway is labeled "36" (360 degrees) and a south west runway might be "22". In the rectangular GreebleCity universe, runway headings would be 90, 180, 270 and 360 degrees with markings "09" (or "9"), "18", "27" and "36" respectively. I made the corresponding runway heading tiles. If two runways are parallel, they are labelled "18L" and "18R" for left and right. I also added those variants. For city planners, a dual runway layout might look like this: >> 27L - - - - - - - 09R << >> 27R - - - - - - - 09L << Another special marking is the aiming point, which pilots are supposed to aim for when landing, which I also added. Lastly, I made some variations for crossings and intersections with different markings. It should print fine with 0.2mm layer height, same dimensions as the original pieces at 3mm base and 0.2mm for the markings on top.
