A1 External Filament PTFE Tube Rest

Holder to keep the external spool holder PTFE out of they way when you're using your AMS Lite. This is very heavy duty and won't slip or fall off while you are printing or inserting the tube. Beveled on both ends to make PTFE insertion painless.

This won't “snap” on, you'll need to slide it onto the end. It's very tight, but it fits!
