Tried to edit the information field, but it doesn't accept changes. Looks like I have to use the comments: There is a second stl now, which incorporates a mount for the standard bowden tube fitting (shape borrowed fro Nick's UBIS printhead)

I used Yellow ColorFabb PLA/PHA. No softening issues after 10 hours printing. But I'm using a crossflow fan, which covers the entire printing area.

Hi foehnsturm. What filament did you use for this print, and are there any softening issues?
