Snap-on Cable Chain for Direct Drive Ender-3

thingiverse

I swapped to direct drive due to friction in my bowden tube, so I installed the Direct Drivinator and then managed cables without a plan until after printing the part. I also learned that extending the extruder motor wiring is necessary after the mod. To minimize screw tightening, I used NG Design's cable chains as inspiration for a solution that snaps on easily. The anchors for the extruder motor and x-axis gantry snap into place. The lower anchor requires loosening screws to slide it in, then re-tightening them afterwards. Note that I rerouted wires from the electronics case to come up by the z-axis limit switch. To achieve this, I drew a rounded curve on the electronics case with the wire protector stencil and then cut it with my dremel. Next, insert the two pieces of the wire protector into place. I used 50 chain links: 21 on the upper chain and 29 on the lower chain. The included gcode allows printing 25 at a time. I'd like to thank the designers of NG Designs for their cable chains and Madau3D for their design inspiration.
