It's a decorative bowl! I printed mine in black ABS at .32 layers, 2 perimeters and around .3 infill (.32 layers because I wanted the "3D Printed" look ;-)I tried printing a similar bowl I found online and it started out bad without support - this one has been designed to look good AND be very easy to print. It was also designed as a nice big print to test my printer out :-)The first file (DecorativeBowlFacetres2.stl) is a more faceted version, the other is highly detailed (I've heard some printers have trouble with very high resolutions) I prefer the high res model as it is much smoother!
