I simply resized the dimensions to fit my machine. Only needed to add a little length to the shelf.
I did not strip my CAM before saving though. They were for 14ga steel with a 45 nozzle.
I forgot to mention, I was not concerned with the 16" OC of the original as I am mounting in a post frame building so my wall girts are horizontal... If you are mounting to standard 2x framing you will need to plan extra blocking or some such.
