Summary

Widened chain, doubled bend radius, added openings and snap in insert. Insert keeps cables in order to maximize cable life, as in commercial cable chains.

Print insert with smallest possible filament width for best results. I used .3mm. Print chain links and inserts and push inserts in from top making sure to match orientation throughout length of assembled chain. Chain can be used without inserts if desired.

I designed this for a new, large, 3D printer I am working on to provide 12 #22 wires for 3 steppers, 4 #18 wires for 2 hot ends and several #26 wires for thermistors, fans and led lighting.
