Derived from an old wood project, modified to fit and work from a 3D printer. Foldable camping table/stool. I've included 3 different “tops”, a basic solid, a circular indentation for beer bottles, can etc., and one for wine glasses. You choose your configuration. 

Infill varies for different parts, with the tops and legs being 25% and everything else at 15%. Attached is a detailed instruction page.
