Chain Creator with Text - refactored

I mostly just re-arranged/refactored the source code. Some of the changes were made just because I consider the code more readable that way.
For example a variable called "l" is very hard to distinguish from a constant "1" in many fonts.
By changing $fn=100 to 30 it made it much faster to render.
I removed a bunch of the extra brackets, substituting indentation, again just for readability.

The biggest set of changes I made I am not sure I am happy with the results or not. Because the slopes overhang by more than 45 degrees some of the surfaces do not print well so I attempted to tweak the perfect shape so that these surfaces would only be 45 degrees. Again, not sure if I like the results or not. It still had some trouble printing on my machine.
You need to print with at least some supports, I was trying to print with only supports from the build platform.
