This Model uses the rotary spool holders from the AMS lite, they can be purchased by following this link:

Please make sure to buy the correct spool holder. This model uses the green spool holder and can be mounted to the right of the printer with the PTFE holder up, or to the left of the printer with the PTFE holder down. I have another model that uses the yellow spool holder found here:

Use a pc4-m10 PTFE coupler and attatch to your printer. The rotary spool holder will prevent the spool from unraveling by keeping tension on the spool and will even retract the filament to some degree when unloaded. The filament will still need to be pulled out by hand before using the AMS, this will NOT fully retract the fillament from the machine.
