CAD Software Anyone know OpenSCAD well enough to fix this file?

I found this rail guide generator on thingiverse, looks like it could be useful. However when it runs it doesn't generate anything. I am unsure how modules work. It appears the code is there, but nothing generates. It was posted 3 years ago, maybe something changed that it won't run on newer software version? If anyone has any ideas to get this working, I think it could be useful

It is just a bunch of modules with no top-level code to create anything. As suggested by the comments, add a line at the end of the file:

rail_guide(tube_diameter=inch(3));

Caution: several of the examples in the comments use "tube_size" where it should be "tube_diameter".

Thanks! For whatever reason now a lot more of this makes sense. Its been almost 20 years since any CS courses.
