If you're like me, you probably installed the drag chain in one continuous loop from the print head down to the chassis, which inherently makes the drag chain get in the way of itself in certain position, even hitting the x-carriage limit switch occasionally. After all that work of running the wiring thru that chain and wire-tucking the exruder, who wants to go back and undo everything to remove a couple links or install some other drag chain adaptor that makes you run the wiring thru it (facepalm).
I present to you a simple way to change the direction on the drag chain by simply undoing the link at the desired location, stretch a tiny bit, then re-attach the links to their respective receivers. You do not have to remove the wires from the chain whatsoever! You will not even notice the wires, and this design allows for infinite adjustment until you get the desired lengths correct.
Please note this part is design with proper clearance for the Z-carriage protusion, so it will NOT friction fit! It was designed to use 3M VHB tape which allows the proper flex needed, and will not pop off on its own.
As a reminder, this part is designed to work with the ever so popular Uxcell 10x15mm drag chain:
On Cura, for supports, I used:
Support type - Everywhere
Structure type - Lines
Overhang angle - 45
Fill amount - 15
Distance X/Y - 1.2
Distance Z - .25
I printed with PETG. I do not recommend PLA for this.
Remove supports, file down, flame polish with a lighter if desired.
