A1 AMS Hub Upper Bracket with PTFE guide

This is a bracket for the A1 printer to hold the A1 AMS Hub, and includes a guide ring for the PTFE tube from the hub to the hot end. I want to give a shoutout to @Viking42 and the A1 series AMS hub bracket which I used and worked great before designing this model. After some time using the A1 AMS hub on the upper mount location of my A1, I noticed the sideways pull on the PTFE tube was causing the sliding outlet of the hub to rub on it's guides, which resulted in a continual squeaking sound while printing. I originally just tacked on an additional piece with a cutout to help guide the PTFE tube so it ran straighter into the A1 AMS hub. After using that for a few days, I decided to go back to scratch and spend a little bit more plastic to make a new mount that (hopefully) improves on a few things, does a better job of integrating the PTFE guide cutout, and matches size with the A1 AMS hub. So a bunch of measurements and test prints later, and this model collection was born. Content
