Large Yarn Bowl. I created this with my wife's input. She's the knitter in the house. I printed this one (https://www.thingiverse.com/thing:688725) for her, but she wanted a bigger bowl. See pictures for size comparison.

Set supports to everywhere, support overhang angle to 70 degrees, and block any supports that attach to the inside of the bowl. Supports should look like the ones pictured. All of the supports that attached to the inside of the bowl failed for me.
