This paper present the experimental research structure “Pringle”, a hybrid structure of minimal surface and its equitangential boundary frame. The background of this research is rooted in the competition winning entry for the permanent tensile cover for the Guatemala relief map, and the design proposal for a semi-permanent tensile cover in a historic courtyard. The successfully accomplished structure right-proofs the equitangential coexistence of a minimal surface within its bending active, annular boundary frame, and showcases the use of their geometrical match in two regards: firstly, the utilization of the strong axis of the annular stripe`s cross-section perfectly absorbing all axial forces from the minimal surface, and secondly, the use of the annular stripe`s weak axis for elastic bending into its selforganized Pringle-shape. Consequently, this paper highlights the theoretical background of the Pringle-shape, its equitangentiality with the enclosed minimal surface, the used materials, the assembly and installation and the retrospective structural analysis.
