Summary

These 2 pieces use the same basic geometry as https://www.thingiverse.com/thing:4289718. But to make them more bowl-like (and presumably more useful) I opened them up to allow for more internal space.

Doing this was fairly easy becuase I use design software that is 100% parametric. This means all that is needed to change the geometry is changing the appropriate parameters. No new or different geometry is created by me - it is all done by the design software. This blog page explains how that works: http://birkbinnard.com/blog/parametric-modeling/.

Both of these pieces printed at 90 mm/sec using a layer height of 0.200 mm. ArcVase 2 printed in a little more than 16 1/2 hours; ArcVase4 in slightly less than 19 hours.
