I made these bowls for my kids to use in their toy kitchen. They are a simple design with no need for supports.
I had some issues along the perimeter of the bowl halfway up. I discovered that my slicer had sliced a couple of layers with loads of small loops instead of continuous one. I fiddled with the extrusion width in the settings (increasing it from 0.45 to 0.48 specifically) and managed to reduce the issue.
Have fun and Be Inspired!

I printed this in PLA, without supports, with the flat part down on the print bed.
