Oh OK. I ask because tinkercad leaves those facets as well. Ask you friend if he can use arcs instead of segments to make the round parts. If not, maybe use more segments. That will make it much smoother and actually speed print time.
Thanks for suggestions. I think issue lies with older slicer software, 3D cad is perfect. I have also considered making reverse "mold" and use that to hammer out dents of real bezels.
