I buyed my "third hand" without a magnifier ... very cheep. The Magnifer i used was part of a Screwdriver set but the outer ring brakes a while ago. So Magnifier glass, incomplete "third hand" and 3D Printer ... what to do? :D Messure it, Scad it - slightly testing its size ;) - slice it and print it. Additional parts: "third hand" Magnifier glass(50mm, 5.5 - 2.4 Convex) 1 x M3 hexagon full nut (DIN 934) 1 x M3 (cheese head) Screw Print it, use it. Instructions, look at the images. For questions comment. have a nice Print!
