Created in Fusion 360. I used PETG to print this. It's a good material because it withstands some flexing (for when you're putting things on the ring) and should be able to handle dishwasher temperatures (which I needed it to do for my set of measuring spoons). The chevron cross-section hopefully provides a little extra strength over what you'd get with a flat cross-section.
The author marked this model as their own original creation.
