I have added a Roland Drag Knife holder to the side the of the diffuser on my X-Carve CNC. This will also hold a Sharpie marker and or pencil. Use a 4mm screw to hold them in.

I purchased the drag knife here for $18. http://www.cnccheap.com/index.php?route=product/product&product_id=88

I am using this to cut vinyl, nothing super thick.

My next option is to design it to make the knife holder removable.
