The release of the A1 Mini came with a unique opportunity for a better Filament Hub for us X1/P1 owners. With the right adaptor it outperforms a majority of the printed ones that were popular. The recent release of the 4-in-1 is more targeted, but that seems to be more out of stock than not. My adaptation is fine tuned from a few alternative PTFE routes, this one to move it behind the Buffer. In this position it replaces the more expensive Hub that allows for up to 4x AMS chained up. The advantage also extends to dry boxes and other external feeds. In this set up it has added functionality as the Buffer will “read” there is external feed when filament is fed into the Buffer if the AMS hasn't been triggered. I designed this to be a fit and forget, there are no permanent changes also. So more printing and less fuss.

Parts required:

• A1 Lite Filament Hub with tab removed
• PC4-M10 fitting
• 51mm length of PTFE (A1 Hub to Buffer)
• 2x M3x8mm screws (Buffer Spacer to Printer)
• 2x M3x8mm screws (Buffer Plate to Spacer)

Fitting Instructions:

• Remove Buffer
• Install Spacer Plate with 2x M3x8mm screws
• Install Buffer Plate to the Spacer with 2x M3x8mm screws
• Screw PC4-M10 fitting onto Adaptor
• Install the 51mm PTFE into the PC4-M10 fitting (all the way seated)
• Align Buffer to the 51mm PTFE and locate tab on Plate/Buffer, the two original screws fit the Buffer
• Reconnect the Buffer to Printer PTFE and then your choice of inputs on the 4way
