CAN Bus Over-wire Cable Support / Strain Relief - The NoGland PG7 / PG07 Gland

On first building my Voron 2.4, I didn't have the proper cable support. Of course I started using the printer anyway, and soon noticed how severe the bend in the CAN bus cable was at the print head. 

This was created as interim cable relief that could be installed without re-running the CAN cable, to hold me over until a proper PG7-based solution was available. Which of course made implementing the proper solution less important… We've all been there, right?  :-)

I used it for a couple of months, and frankly, it was surprisingly effective. It was designed and tested for the EBB SB2209 with Galilio 2 and CAN bus on a Stealthburner, but should work for other configurations. It is sized for the relatively large BIGTREETECH cable ends, so should work with most CAN cables.

INSTRUCTIONS:

• This is thin enough that it makes sense to just print with 100% infill. And with the filament choice and other settings that you use for structural parts. 
   
• Open it up at the modeled cut in the side and fit around the cable end. NOTE that this is asymmetrical to match asymmetrical cables and fit better in the print head. Orient it to fit best in your setup, usually with the thick side out.
   
• Plug the cable into the EBB SB2209 or other board.
   
• Zip-tie at the top. You're done.
   
• The XT30 (2+2) CAN cable connection is strong, and the CAN cable port on most boards is robust. So this relies on those connections to support more gentle cable bends near the hot end.
   
• This probably has about the same friction where it contacts the cable as a cable chain does on the cables inside it. In other words, the whole reason you switched to CAN bus is a good reason to not use this forever. Swap it with a PG07 at some point!
