I had a stack of note-paper without a binding, so I needed something to put it in. I created this to hold it, perhaps it is useful to others as well?
I don't think you need any special settings, printing should be straightforward.
Don't make the bottom too thin, it'll be weak (but still hold the paper)
I printed the blue tray on a prusa i3mk2 at the finest settings (normal should be fine though). The side walls are very thin, which may explain the "turning" artifacts on the walls...
