Centauri Carbon Cable Arm - Vented Riser

UPDATE 11/3:

Elegoo has acknowledged the issue and designed a new cable for the printer. If you want an Elegoo supported solution please see this post: https://www.reddit.com/r/elegoo/comments/1onc5ee/response_to_the_feedback_on_the_print_head_cable

Credits:

A large amount of credit to baconmilkshake for his insistence that this is a serious issue that needs to be corrected. Into The Mild for his openness and ability to create usable and workable models and solutions. And for this riser, credit to Raymond for originally putting a cable arm on a riser and giving the community the idea to look into it. 

The opencentauri discord server has been tracking the USB cable issue and doing what we can to attempt to mitigate this until Elegoo gives the community an acceptable response. If you want to track this issue or see what the community is working on, it's the place to be.

Note:

I do still recommend the Sturdy Riser version of this arm as it has more clearance for the cable and PTFE tube. If you're printing in brittle filaments, the clearance of the vented riser will definitely not be enough as there are some tighter angles in the back left portion of the printer. Also you find the cable/PTFE rubbing against the top glass annoying, there isn't much I can do about that due to the height of this riser. Please print my other version if you want a more permanent solution: https://www.printables.com/model/1450583-centauri-carbon-cable-arm-riser 

Requirements:

To utilize this cable arm properly, you will need the following:

1. You will want to install the cable strain guide from this link, you only need to follow the instructions to install the guide onto the toolhead: https://www.printables.com/model/1447575-elegoo-centarui-carbon-usb-cable-strain-guide-and
2. Printed parts from the Vented Riser Remixed here minus one of the frame pieces
3. 2 m4x8 or m4x10 screws, the 10mm screw might be too long to attach the arm mount to the frame.
4. 1 m4 nut
5. 2 m4 washers
6. New PTFE tube (The stock one may not be long enough, but it also might be)

Suggest Materials:

• ASA/ABS: This will easily handle the temperatures inside the the chamber of the CC
• PETG (CF/GF): This should be sufficient for the internal temperatures of the CC, unless you have an active chamber heater you may want to go with ASA/ABS. This is what I used.
• Polymaker HT PLA: This is the only PLA I would recommend to use for a riser on the CC
• Other: If you wanted to use Nylon or PC for this you could, but is definitely overkill and expensive

Printing:

You can use whatever print settings you want really, it's a pretty easy model but I provided a 3mf anyway. You will need to print out the following items:

1. 1 - Back Mount Frame
2. 1 - Cable Arm Mount
3. 1 - Cable Arm
4. As many cable clips as you need

Assembly:

I believe Assembly of the riser is pretty self explanatory so I will just provide instructions on attaching the cable arm and mount:

1. Determine how high you want the cable arm to be, you can rotate the Arm Mount either up or down, and install the Cable Arm to the mount on either the top or bottom. You can reference the pictures in the following steps to see where I installed mine.
    
2. On the back mount frame drop the m4 nut down the channel on top. Then install the Cable Arm mount in the chosen orientation.
   
   
    
3. Attach the Cable Arm to the Cable Arm Mount using the m4x10 screw, and both washers. The Cable Arm has self tapping threads that should grab on pretty tight. Do not over tighten this screw, you want the arm to be able to move smoothly.
   
   
    
4. Move PTFE Tube through the opening in the back and through the enclosed Cable Arm hole and put the USB cable through the Cable Arm hole with an opening. 
   
    
5. Connect the PTFE and USB cable with the cable clips.
    
6. If you find that the cable drags against the opening where it's routed, I cut a small piece of 5mm Inner Diameter PTFE and placed it on the cable at that point.

UPDATE 10/27

1. Added a variant for an M5 screw

I took the vented riser model and added the PTFE tube arm to support the cables higher to work with the USB Cable Strain Guide.
