This is a stand alone adapter arm designed to fit a 20 x PC4-M10 pneumatic male straight quick connector with thread M10/6mm. Its made with 4 3mm/6mm holes in the bottom for matching magnets so that it can be placed where ever you need it on the metal sides of your printer. In my case, I need to relocate my adapter depending on if I'm using my side mounted spool.

While the magnets work well its not super super strong so if you have a lot of pressure on your tube this might not work but, seems to do the trick for general use.

The Connectors I used can be found here
