Place your AMS face-down on the side of your printer when other placement options are lacking. It's a very compact placement. Surprisingly the AMS works fine in this orientation. When the AMS is placed in this way, you can easily pull it all the way out in front of your printer when it is time to swap filaments, and you won't need to disconnect the AMS cable or tube.

This is a plate to cover the back of your AMS hub. It requires some glue on the edges to stay on the AMS hub. The front of the AMS hub can be stuck on the left side of your P1S or X1C printer with double-sided tape.
