Nathan K5LA Train Horn

When a kid spends half an hour excitedly explaining the differences between two different models of industrial signaling device to his speech therapist, in particular why one of them is his favorite, well...

I was looking for a K5LA train horn model to print, and the one posted by Manimal was very close to what I wanted but when I scaled it up I just couldn't get it to print. So, I imported it into OpenSCAD and reconstructed it with special thought given to printability. Tolerances are set up for scaling it so the longest horn is 160mm long, bolts are separate so you can easily print them in a different color from the body, and almost everything that would be a pain to print has been broken up in a way that makes it easy to both print and assemble.

How many of each component to print is indicated in the file name.
