The file 'Third Hand – Helping Hand – Solder Assistant 3D Printer Model' is (123dx,stl) file type, size is 3.5MB.
I was looking at the complete third hand with base, and didn't like how small it was, and also it was pretty expensive for what it is. So I just bought the hands and drew up this base to print.
You can also download sections for the arms and print the whole lot if you're really keen. I figured at $3-4 for the whole thing, including alligator clips, it was worth just buying them.
The larger size (right on 200mm) is for if you are glueing the arms in, the hex area is .5mm wider (face to face). If you have a resoldering air gun or something that can get the base to soften after it's printed, use the smaller size, and then heat the hex area on the base, and push the arm in that way.
