Ender 3 / 3 Pro Cable Chain

thingiverse

This was designed for the Ender 3 Pro and inspired by similar models out there, but as an engineer, I couldn't just reuse someone else's and had to make my own. The purpose of these are to keep cables out of the way of the build plate and to provide strain relief for the wiring. The chain links themselves are all the same piece, just 2 different sizes, and snap together in a pattern (1 up, 1 down, repeated) so that they can be installed or removed without any disassembly of the printer itself, with the exception of temporarily removing the bed to replace the wiring support with a new one. - The base that supports the start of both chains slides onto the aluminum extrusion after you feed the XZ wires through it. - The XE chain is designed so that it fits both the wiring for the X-axis/hot end, Extruder, and a standard raspberry pi camera ribbon cable. - The XE chain end snaps around the bottom of the Extruder motor, and has provisions to route the hot end wires towards the machine head and also has a filament guide that reaches around. I also have a mount made more recently to be used if you have deleted the extruder from this location in favor of a direct drive setup like I have. It uses the same mounting holes as the extruder motor and reaches down to connect to the chain at the same point that the original mount did. - The Y chain end replaces the rear-left wire support. You will have to remove the bed to install this, but that is very easy to do, and there are provisions to feed new zip ties around the wiring as needed. All of my designs are unpaid passion projects that I choose to share, and I provide mesh models for free, but if you'd like to support me and my work, donations are greatly appreciated.
