Create Google Sketchup files that can be printed on a 3D printer

Before I ever had access to, or knew what a 3D printer was I used sketchup for various reasons to build things, and while I know there are better programs to use to build 3D designs its simplicity mixed with my experience covered all of my possible 3D needs. Once I found out about 3D printers, though, there were a few files, that I thought would be really need to convert into real physical objects. The problem was that sketchup did not provide a solution to convert my files into an accessible format for 3D printers. After some searching on the web, I found some software that I would like to share with you so that anyone with a knowledge of google sketchup can create their own 3D prints. 

The only software aside from google sketchup is a program called 'topescope which lets you view your completed files before you send them off and spend money on the prints.

Supported formats are stl, dxf gts, nff, q3o, obj, off, ply, tri, uo

I have also attached the ruby files needed for sketch (see next step). There are two of them and I will explain where they need to go

Step 1: Add files to sketchup

There are 2 ruby files that need to go inside the sketchup applications folder. Afterward restart the program. You can access the files from my google docs with this link since I can't seem to upload ruby files onto the Instructable website. The files should go right inside the Google SketchUp (your version) folder.

There are 3 files in the photo but you only need 2. One of them is another unrelated ruby file.
