Geometric bowl created using cubohemioctahedrons with roses on the flat faces. Prints with supports touching buildplate and can be scaled up or down.

The bowl in the photo is printed in Bambu Lab Marble PLA Filament link: https://shrsl.com/4ecvf

I also have a similar taller bowl without roses that prints support-free and can be downloaded here: https://than.gs/m/1000813
