So we are 3d printing , right? So why we priting wire chains like we using traidnatioal manufacturing? So here is my answer.
Prints as one peace. No supports needed. Wires can slip in, no need to thread wires through. Then connect ends with m3 to m2 screw. Connection point is 0.5MM form Tung to back of link, then use end link fo finish.
Sketch up file include for easy assembly or modification
If any one has ideas to lessen tolerance, please let me know!
