The new Palette 2 comes with an oversized PTFE tubing which slides into the unit. After just 2 weeks of use there was wear and tear visible. I have created this Filament funnel so you can use the normal PTFE tubing (Prusa MMU 2.0).
You will have to use a 1/8'' Threaded Bowden Coupling, since the PTFE has to reach the funnel.
You will need to give the outgoing filament a small help when it reaches the funnel. Don't forget to set your new length for the PTFE tubing in the unit. You will have to measure this from the unit - original end of tubing).
