KOBRA 3 MAX COMBO CHAIN MEGA HEAD UNIT

My original design was mode for the Anycubic 8-in-1 PTFE Hub. However, I had a request to modify it so it can support some of the 9-in-1 Hubs. The largest one requested was to support the Kobra 3 Combo | 9 Position Bowden Tube Hub

My original KOBRA 3 MAX COMBO CHAIN for Anycubic 8-in-1 HUB

Plate 1 - HEAD UNIT - Large  9 Position Hub

Will allow the large hub body to remain connected when you unscrew the Mega Head Unit (Hot End Cover). The Larger version will stick out a little in the front. That was the only way to allow the cover to be removed without removing the hub.

Plate 2 - HEAD UNIT - Medium  9 Position Hub

Will fit the large hub but will require the hub be unscrewed to move the Mega Head Unit out of the way when working on the hub.

I have created a chain to route your 8 PTFE tubes and the USB cable for the hot end for your Kobra 3 MAX. As you can see in one of the pics all of my test models to come up with the finished product. It took a lot of trial an error to get it so it would flex enough but not too much. Enjoy.

I used 10% infill for all parts except for the mount and head unit. I will be making a new Mount model to better handle the pressure. I've seen lots of pics of that part snapping. 

I needed a clean way to route the 8 PTFE tubes and USB cable for my KOBRA 3 MAX. There was nothing available out there. I found a couple of cable chains for the Kobra 2 and one great design for the KOBRA 3 MAX. Only issue with the KOBRA 3 MAX chain was that it wasn't made for connecting to the 8 in 1 hub or holding that many tubes. 

The original designer did not have an 8 in 1 hub to be able to make a larger version at the time. I didn't want to wait and made my version in Fusion. If you are only connecting a single PTFE tube and the USB cable. I recommend using LefevreLucie's model it is much smaller and uses less filament. But if you need to connect to ACE units this works great. 

I tried to name the parts so they would make sense on how to connect them. But there was a request for better instructions. Let me know if the attached instructions are clear enough. Also look at the pictures to see it installed on my printer.
