Filament guide with a longer arm to better fit all common filament spools and that is able to sit next to the MMU3.

Adjusted the filament guide for the original injection molded spoolholder to fit next to my MMU. Now I am able to speedload one roll of filament into the MMU on slot 5 and use the “airbuffer” so I don't need to use the MMU3 buffer for singlecolor prints.
To make the “air buffer” you only need two pieces of about 5-10cm PTFE tubing that came with your MMU3. Insert one into slot 5 and the second one into the PTFE adapter.
Bill of materials:
3x M3 nuts
2x M3 screws 12mm
1x M3 screw 18mm
PTFE tube 2x 5-10cm
