Bambu AMS Lite Hub M10 fitting adapter

After discovering that I could use a Bambu AMS buffer along with a splitter instead of having to buy the AMS hub, I found I wasn't happy with the quality of 4-1 splitters I was printing myself. A simple solution was to order the the Bambu AMS Lite Hub, which itself is basically a 4-1 splitter. As its output tube is 4.5mm OD, I created an adapter that will attach to it and allow you to use a M10 fitting on it.

You will need:

• AMS Lite Hub
• A PC4-M10 Pneumatic Fitting
• 2 Bambu spool holder screws

You will need to snap off the magnet (as shown in the picture) and use your nips to trim it flush with the rest of the body. Insert the hub into the adapter offset by 45 degrees, then twist it to lock it into place. Tighten the M10 fitting down well so that the back of it mates with the exit tube snugly; be careful not to overtighten and break the adapter.

I made a mount for it so you can attach it to the rear of the printer; a short piece of PTFE will go straight into the buffer, helping to prevent feed/retraction issues. However, the ideal orientation for a direct feed into the buffer has the splitter directly mounted on the back plate. Some thin double sided tape (like several brands of super glue tape) on the mount will work perfect. You will just have to remove the buffer if you want to pull the tubing after you mount it this way.

I'm also uploading a blank mount so you can modify it to attach wherever you want.
