This is a more customizable version of the low poly bowl by Markus. As a starting point for customization, you can closely match that model by setting wt=5.0; sides=10; h=37.5; od=157.5; bend_height=13.5; bend_angle=33; and r=2.0;
I mostly wanted to be able to do smaller bowls/thinner walls, but it should work fine for making larger bowls, as well. The model supports going as low as 3 sides, but the result lacks much of the interest of higher side counts.
Unless the bend_angle exceeds the overhang your printer can do at the chosen layer height, no supports are needed.
The author remixed this model.
My remix is highly customizable, including setting the wall thickness, the number of sides, the amount of rounding at the top, the diameter and height, and the angle of the base of the bowl to the ground.
