This vase was a model I compiled for fun, but also to make a functional piece. The bowls in the fourth picture are not with the design, except for, of course, the centerpiece of the Triangle Vase.
Level your print platform, add supports and rafts - and BOOM!, there's your all new Triangle Vase. Just a note, supports can be difficult to remove from the bottom due to the 4 knobs. By the way, these make the vase look like its floating, in addition to making it unique.
