This is a fast design. Just trying to made a openscad script that fits in a tweet (280 chars) and the result is this mini collection of bowls.
See on Twitter
Print in vasemode/spiralized and scale in your salicer as you need. Useful as a container, planter, penhoder,etc...
I encourage you to downbload the openscad files and try to find nice variations.
Hope you like it
