What is this for?

Recommended Posts


Thanks for that. There's nothing in the manual about it and its not shown in the "What's in the box" page. I assumed it was some sort of test or calibration aid.

Just had a look and I can see where it fits. It doesn't want to go in though, but its printing at the moment and I don't want to disturb it too much. I'll fit it later.

Actually, the filament guide is very good to use even for single extrusion.

When having fresh rolls that barely fit a spool they are helpful, as well as for very long prints when the a complete roll of filament is not perfectly rolled up.

See this thread for more examples:


(Ultimaker started shipping it after I, Ian and others reported that is was really needed/useful).

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
