Parametric Vape Tank Bumper.

After I broke the glass on my tank a second time, I decided I needed a protective bumper for it.
So I made one for my MILO 2
This is my first attempt at OpenScad, but it should be customizable for almost any tank size. All the variables are at the top of the file.
The STL file is for the MILO 2 tank from IStick created off the scad file.

*Edit 11/18/16
I renamed some of the variables and organized them to make the file customizer friendly.
