A1 PTFE Support for Spoolholder

Simple support for the A1 spool holder to align the PTFE tube. I found it annoying that it moved in all directions, now its aligned, still rotatable. I modified the original file (https://makerworld.com/en/models/660698?from=search#profileId-587853) to be just one part. Looks a bit cleaner, nothing changed in the way it works.
