faceted vase: https://www.thingiverse.com/thing:18672
twist vase: https://www.thingiverse.com/thing:124175
These two vases are done using a technique where the file is printed as a hollow surface, and the entire outer wall is printed in a growing spiral pattern, meaning that the walls of the vase are one continuous strand of filament. The twist vase took a couple of tires because the base wasn't adhering to my printer bed well, but the finished pieces are lovely and, as an added bonus, they both do hold water! I liked that they're quick to print too, around an hour and a half each.
