First test with OpenSCAD

Test Thingy Please Ignore
---------------------
So I made an update to my first test and also included my OpenSCAD script. I just watched a few basic tutorials and combined some of those concepts.

* I used 3 primitives: **Cube**, **Sphere**, and **Cylinder**
* I used 3 transformations: **Translation**, **Rotation** and **Scaling**
* I used 2 CSG operations: **Difference** and **Intersection**
* I then used some variables and built it as a module

I've enjoyed working with OpenSCAD and hope to make some more.
