This is a PTFE Tube Guide for the A1 Mini and the Top mounted Spool Holder I designed.

It snaps onto the existing PTFE Adapter of the A1 Mini by using a short piece of PTFE Tube it creates a Guide to rout the filament into the right direction.

By using this PTFE Guide and my top mounted Spool Holder you can print almost the full height of the A1 Minis build volume.
