When I designed this bowl and vase, I was going for a 'cut glass' look.  These were both printed on my FlyingBear P902 printer with transparent PLA filaments.  The bowl measures 165 mm dia. at the base, 196 mm dia. at the top, is 100 mm tall, and has a maximum diameter of 217 mm.  The vase measures 56 mm dia. at the top and bottom, is 170 mm tall, and has a maximum diameter of 78.5 mm.
UPDATE 12/26/2019:  I made a few small changes to the STL model of the bowl.  (The new file has the name 'Faceted Bowl 2'.)  In this new model, the overhang angle of the lower faces of the second and third row of facets is a bit steeper, which should help it print better.  Also, the bowl is no longer lying on its side.  Otherwise, the new bowl is identical to the old one.
Note that the STL models are solid; that is, in the STL models, the bowl and vase are not hollowed out. To print them properly, you MUST use the 'spiralize' or 'vase-mode' settings in your slicer. This setting will not print any infill or top to the bowl or vase…
