PCB Holder Mrk II. (Q34914)

I was inspired by zignig's Printable Desk Clamp http://www.thingiverse.com/thing:683 . I used hex nuts instead of square nuts because hex nuts are more common. All the parts are easily available at hardware stores and hobby shops. The total cost is about $4.50 for this clamp compared to $50 ones. It is used for holding circuit boards at comfortable angles, hobby modeling, and holding stuff. Enjoy. The picture of all parts does not show two nuts that I had already hammered in but I did not want to take them out. Also it does not show 20mm brass tubing as I already hammered some of them in.
