One of the things which triggers a bit of latent OCD with me is wire management. I have done my share of crap wiring jobs and one thing is common to all of them. When it comes time to troubleshoot/upgrade/replace something, it's nothing but cursing all around. I hope I learned a bit from having to rebuild a few projects just to clean up the wiring, so when I started assembling the electronics for my Voron 2.4, I knew I would be in for some problems, I just was not sure what I was gonna do about them. Fortunately there are great designs in the community which I am using or remixing to fit my printer, and what I'm trying to achieve. I thought I would make a post to cover some of the things which I am using or plan to use (or am working on) to help with wire management in a Voron printer.
#1 Wire Duct (REMIX)
I didn't need to do anything to RyanDam's Cable Management Duct, other than to make it a bit longer. I'm extending them so I can run two and cover the full sides of my Voron 2.4 350 electronics compartment. I plan to post these as a remix on Printables soon.
#2 WAGO Mount With Labels (REMIX)
The stock 2020 rail WAGO mounts included in the official Voron files fit the WAGO 221-415 blocks perfectly, so much so that I had to break the first one I printed to remove the precious WAGO's when I iterated the design, and needed them out to test it. The original Voron design is great, and so I used it as a basis to remix some changes. The first change I made was to create a 4x415 block (and a 2x415 block). Then I added some guards and label holders to it. The guards are there for mains hot and neutral lines, to give them a bit of extra protection from getting bumped. The label holders are designed to be used with Brother P-Touch 12mm labels. Since the labels may not stick well to a bumpy printed surface, they will be retained by small frames which will slide over them.

#3 Low Profile Cable Routes
I'm not sure what to call this one, but it really tickles the old OCD gray cells. I want to ground my DIN rails, which as far as I can tell just sort'a float in the stock Voron. Technically the DIN rails are connected to the bed rails, so would be grounded to the frame, but it's not as direct a path to ground as just connecting them up to a ground point. Additionally the ground wire to the SSR would also ground one rail in the stock config (via the required metal DIN mount for the SSR). The SSR in my kit has correct metal DIN mount, but the SSR case has a note that it should be grounded to the DIN rail (though if it's grounded directly I'd think it would be about the same). In any case, I'm going for more grounds the better, and so designed some cable routing things to help my ground wires reach the DIN rails, and then route back to a grounding point in as low a profile way as possible (and avoiding the sharp edges was also a goal.
This is still a work in progress but it's coming along. The wire guides will mount with VHB tape, and unfortunately will block me from adding a cable duct wherever I locate these, but I plan to just keep them in one area. I used a star washer to dig into the metal on the DIN rails with a washer over that and finally the crimped on ring terminal, I plan to ground the frame similarly. Getting the ground screws installed in the DIN rail was a whole 'nother story, which I may write up in the build log, but the short of it is, roll in M4 nuts would be much better suited to hold the DIN rails than the cheap M4 T-nuts included in the FYSETC kit. I used are some 16AWG wire to ground the rails, which will run back to a grounding point.
Once I get these wire guides finalized, I will post them on Printables. There will be multiple sizes of straight or 90° guides, but only two basic formats (single and double wires guides). There is also a double wire "bridge", which will go over one end of the DIN rail and keep the wires off the sharp edges of it as they cross over. The wires I plan to run over the DIN rail are ground wires, so I don't think it would be an issue.
