CAM packages can be expensive and require a commitment to a long learning curve.  I decided to create few step-by-step write-ups on three of them.  

To take you through the various cam packages, I created this part.

I created the DXF file in CorelDraw and exported it so that it could be imported into each of the CAM packages.

You can get the DXF here:

The stock I used was 1" x 1" x 3/8" thick CPVC plastic.  We are not cutting all the way through the stock so you can use thicker materal, such as 1/2" plywood or MDF.
