Lubricator for Ultimaker

this is an upgrade for the ultimaker to speed up your prints.

you might freak out of this idea but it helped me alot
I went from 100mm/s to 225mm/s (for simple objects)
and I went from 80mm/s to 150mm/s (for complex objects)

I spray oil in the bowden tube of my Ultimaker...... yes I do.

The Ultimaker is very fast because of the light weight on the hotend (as you know) But this comes with a down side, because at high speed the frixion in the bowden tube becomes bigger and this leads to
