I just published our Free CNC Router Plans for our 12" x 11" X 4" travel machine. It can be built out of MDF for $105.00 or cheaper and out of HDPE for $220.00. Our simple but strong design is easy to build. You can see some of our reviews here on the zone. I will have the supporting parts for sale on our website soon. Our plans provide important dimensions, materials, and part numbers. Let me know what you think. Plans are located at http://freecncplans.blogspot.com.
