There was one extra vector line in the original drawing that was creating a problem for my CAM software when I was setting up my cnc router operations. So I removed the line in illustrator and republished it to a .dxf file.
You can find the original instructions here: http://www.thingiverse.com/thing:776 ... I set mine up for my cnc router table. You'll need to do this as well. When the parts are cut and assembled, I chose to use a piece of dowel between the clamp and the wing nut.. I also chose not to drill the hole for hook-hanging because these are going to live on my table 24/7. There are many options here, so don't take it too literal. Use what you have. Do reference the original thingiverse page for more photos and the object's history.
