Third hand PCB vise with ball joint

thingiverse

Derivative of "Vise Left" with a ball joint to replace the magnifying lens of Radio Shack's Helping Hands: http://www.radioshack.com/product/index.jsp?productId=3928375 Instructions I printed with external support turned on, which only prints under the shaft and ball joint. Easily cleaned off with a knife and file. I used 1/4" rod, so I bored out the pair of holes for that with a 1/4" drill bit by hand, mounting the bit in my cordless drill and rotating the part by hand around the bit. I then widened the holes with a small hobby file until the part slid easily on the rod. I mounted the part in the Helping Hands without tightening it too much, and rotated it all around so the metal of the mount smoothed the ball out. Tighten down and use!
