Remix of RyanDam's Cable Management Duct for Voron Printers Version 3.2

Updates:   The v3.0 updated the ducts with an extra bit of material which may help strengthen the tines, and a new zip tie mount, which works with 2mm zip ties.  The updated zip tie mounts are orientated so the zip ties can be placed perpendicular to the wires (which should make wire management a bit easier).  With the v3.1 update, snap in endcaps were added, which cover the open ends of the ducts.  The endcaps will not work with CMD_V3_1H_BRIDGE_SHORT.stl, but they should work on the other ducts. The endcaps are included in the 3mf.  On 5/8/2025, with the (current) v3.2 update some additional spacer clips and 45° ducts were added.  Thanks again to some very helpful feedback and suggestions from Steiner-SE for collaborating on the updates.
 

Since these models are are wire ducts, and are used with electrical components, if you use these models, it is at your own risk.  These models will not meet code requirements, so use your best judgement if they should be used in your application or not.  If unsure, consult an expert or professional (not me).  In general, I suggest using a flame retardant filament for any prints that will hold electronic components.  

The version here was designed around a Voron 350mm printer build, though the ducts are somewhat universal with other build sizes.  But if you are building a 300mm Voron, please be sure  to check out Steiner-SE's remix which has been fine tuned to fit the 300mm printer size.

The description below is mostly unchanged from the version 1 models, since they are fully compatible.  I did not print all the new V3 models, since my V1 models are working fine, but I did test print a few new V3 models and they were fine.  The changes between V1, v2 and now V3, did not modify the footprint or lids.  There are some additional short and long bridges, which are now included for people building smaller printers than the 350mm R2.4.  The pictures of my build are the v1 models, though it is hard to differentiate them from the new v3 models, unless looking at a close up.  

Description:

This Remix of RyanDam's Cable Management Duct for Voron Printers includes a number of custom ducts which I am using in my Voron 2.4 build (350mm).  Thanks to the original author for the excellent design of the ducts, which this remix is based on! 

Included here are several customized ducts which may help with cable management in a Voron build.  These ducts were designed for a 350mm R2.4.  If you use these with another printer, or a different size Voron 2.4 or Trident, please post pics and feedback.  These models were designed with help from the STEP file from the Voron Github, which I used to set the layout of the ducts.  

Note that these work with 2mm zip ties (they may also work with 2.5mm zip ties, however that is untested.

A Bambu Studio 3mf is included, with all the parts on several plates.

There are multiple ducts included, which are designed to go over the DIN rails, and these parts include “BRIDGE” in their names.  All the bridges have integrated supports, so they should be printable without using supports.  But there is still going to be a small area that requires bridges (so supports can be used if needed).  There is a 0.2mm gap between the integrated support and the models, so a 0.2mm layer height is recommended for the “BRIDGE” parts.  The covers for the “BRIDGE” parts have print in place hinges, so if you find they are welded together when printed, it will be helpful to calibrate flow and horizontal expansion, as well as adjust the temps for the filament used. 
 
The 90 degree full bridge ducts come in two sizes, REG (regular) and LONG (which is, you guessed it, longer).  If using a standard layout, with the PSU on the right side, the regular size 90° bridge would be best fit on the right hand side (RH), to allow the power supply stabilization bracket to pass.  

I set my ducts up so that the high voltage AC wires, and the low voltage DC wires, would stay in separate ducts.  To do this, I used two half ducts (one for the AC, and one for DC), on the center duct which crosses the lower DIN rail in the pics, which is nearest the power supply.  I also printed the AC ducts in orange so they would be distinctive as a reminder they contain the high voltage AC wires.  There is a remix here, with the covers for the box with AC warnings on it.  

Below is an image, which shows which STL files I used, and where they go.  Note that this image was made  for the previous v2 models, so the prefix for the files has changed to “CMD_V3_1H_XXXXXX”, since the image was made.  Also, the duct covers which have the “High Voltage” warning (black with orange text), shown in the pic are a remix.  

There are plain and logo versions of the covers included.  

I chose PETG for the combs, but the prototype was printed by another user in ASA, and seemed to be OK.  In general, I suggest using a flame retardant filament for any prints that will hold electronic components.  But as always, use your best judgement, and maybe run some smaller test parts in the chosen material, to see if the tines will be strong enough.  Broken tines should be a thing of the past however, since after the V2 update they were thickened up - and that change has been carried over to V3, which adds even more reinforcement for the tines.

I used 1mm thick VHB tape to secure them, but just note that once placed, they won't likely be going anywhere soon.  I installed the stepper wires with 4mm braided PET expandable sheathing, and I used some Brother P-touch heat shrink labels to secure the ends of the sheathing (labeled with the wire designation).  

Parts are not oriented for printing (BUT there is a Bambu Studio 3mf with all the models, which is set up for printing).  The 3mf should be compatible with Orca and PrusaSlicer.

Feedback is welcome, and if there is a problem I will try to fix it as I have time (but this project is no longer a top priority for me, so it may take some time).  My Voron is currently in storage, so if you have an issue,  please provide as much detail as possible.  The STEP files are included for easy remixing.  If you remix them, please also credit RyanDam's original cable duct design, which this is remixed from, and send me the link, so I can add it to the description.  

If you print these, or use these, it is at your own risk.

REMIXES and RELATED MODELS:

In the remixes (and linked below), you can find covers for the AC box, which has an inset printed label, as well as a WAGO box which can hold two 221-415 connectors, which I am going to use for 5V DC distribution.  I have also linked (below) some single and double wire guides which I am using to secure my ground wires.  

You can find some additional low profile wire guides here (I used these to secure my DIN rail ground wires):

Thanks for looking!

Changelog:

9/8/2023: Thanks to feedback from AlexIsMakingThings, I'm going to rework the bridge parts, so hopefully they can be printed without supports.  There will also be a bit more clearance to the DIN rail as well (just an extra 0.8mm).  I expect the redesign to take about a week (or two) to test and update the files.  In the meantime, if you need more than 7.7mm of clearance (including 1mm for the tape), between the acrylic floor and the top of the DIN rail, you may want to wait for the updated bridge parts.  (These are now updated - see below)

9/9/2023:  I updated this with a longer PSU stabilizing bracket, which I forgot to add earlier.  It just extends the 24V PSU out a bit more if the ducts are placed behind it.  It worked in my build, which it was designed for, so I cannot say if it will work in every build, but it's there if you want to try it out.  The file is named:

PSU_Bracket-4D.stl

9/15/2023: The “BRIDGE” models which span the DIN rails have now been updated.  They can print without supports and use an integrated support that should snap off.  They also provide an extra 0.8mm clearance to the rail.  The updated models are:

• Cable_Management_Duct_Remix_DUCT-FULL-BRIDGE__6B.stl
• Cable_Management_Duct_Remix_DUCT-FULL-BRIDGE_LONG_6B.stl
• Cable_Management_Duct_Remix_DUCT-FULL-BRIDGE_90DEG_LH_6B.stl
• Cable_Management_Duct_Remix_DUCT-FULL-BRIDGE_90DEG_RH_6B.stl

These replace the previous models, which required supports.

11/25/2023: A folder named “Bridge Parts Without Supports” is added which contains the bridge parts, without any pre-made supports.

10/1/2024:  Major UPDATE - Version 2.0 rev 6B is released.  Thanks to some very helpful feedback and suggestions from Steiner-SE, I decided to make a Version 2.0 of these models.  The new version has the following improvements and updates:

1. Thicker walls on the tines (this was requested to help avoid them breaking off)
2. Deeper slits over the bridges
3. Indexing tab on the bridge covers (which helps to set them in place)
4. A new zip tie clip (for running wires on top of the bridge lids)
5. There is also a new shorter T and a short bridge.

Update 4/9/2025:  Updated to Version 3.0 .  Thanks again to Steiner-SE, for the suggestion for this version 3.0 update.  The new version has an extra bit of material which may help strengthen the tines, and a new zip tie mount, which works with 2mm zip ties (possibly with 2.5mm zip ties as well, but that is not tested).  The updated zip tie mounts are orientated so the zip ties can be placed perpendicular to the wires (which should make wire management a bit easier).

Update 4/18/2025:  Updated to Version 3.1 .  Thanks again to Steiner-SE, for the suggestion for some endcaps for the ducts.  The caps just snap onto the ends of the ducts.  They may not work with CMD_V3_1H_BRIDGE_SHORT.stl, but they should work on the other ducts. The endcaps are included in the 3mf.

Update 6/10/2025:  Updated to Version 3.2.  Thanks again to Steiner-SE, for the suggestion for some 45° ducts, which were needed in a 2.4R2 350 build.  This update includes several types of 45° ducts, and some spacer clips which may help with aligning the ducts.  The updated files are included in the 3MF profile (cmd_v3-2_2B_base_models.3mf).  The STEP model for all the V3.2 Rev 3C models is also now uploaded (CMD_Remix-V3-2_DUCT-2C.stp).
