Sunlu AMS Heater Arm

I really like the Sunlu AMS Heater, however, when I am opening the AMS to change a spool I was having a hard time keeping it open while removing the filament and spool.  Essentially I needed an additional arm, so I created one.  The arm is long enough that it will hold the AMS Heater wide enough open that you can slide a spool out without having to open the cover any wider.
