I modified the original PTFE Extender with 5 PTFE tube holders for those who are using the AMS Lite along with an external spool for filament types not recommended for use with the AMS Lite (TPU, abrasives, etc.). I also shortened the standoff for the black toolhead cable to provide more clearance between the Z-axis upright so that it does not rub or catch.

There are 3 print profiles: regular fit, tighter fit, and looser fit to match personal preferences.

I also recommend adding the two prints below (I have no affiliation with the creators) for the best routing of the cable to the toolhead.
