This is a remix of this design . The solution was clean but there are some minor improvements that can make it slightly more stable on the spring alignment and also some QOL improvements.

Optional: I have added a ptfe removal tool as I find it difficult to remove the ptfe tube from the ams lite filament hub. You will need to insert the ptfe tube before you connect it to the ams filament hub. if you don't intend to use it, you can delete it from the plate or you can download the stl.

Things to note:

1. Cut the protruding plastic of filament buffer splitter then sand the round one until it can fit in the ptfe tube connector.

Here are the improvements:

1. Add base chamfer underneath the spring attachment to ensure the spring doesn't misalign.
2. Cut some of the underside in the filament buffer splitter not to obstruct the ams cable connector when plugging in. Also reduce the right side to be able to hold and pull the filament buffer if needed to.
3. 
4. Extend the cut to be able to access the ptfe tube connector in case you need to remove the filament buffer splitter.

Added picture on how the small block is installed as a PTFE removal tool. This is helpful if you have multiple AMS especially if you have 3-4 AMS. Removing the PTFE is very difficult using finger.
