Printed a small copy of the bowl shown in the screencast example for my customizable Bezier bowl. Printed in Colorfabb 1.75mm woodfill filament on my Printrbot Simple. 0.27mm layer height, 2 walls, 5 floor layers, no top/infill.

This filament does flow much more loosely than regular PLA. I had to increase retraction and solid layer speed in my slic3r settings significantly to get a good print. I think it was worth the trial and error, though, as the results are beautiful.
