The Materials Property Open Database (MPOD) is a unique open-access resource for Materials Physics research and education. Longitudinal materials tensor representation surfaces for selected physical properties of alpha-quartz crystals, (i.e. its elastic stiffness and piezoelectric effect) were visualized at the MOPD website and corresponding 3D print files created automatically by a simple click of the computer mouse. The usage of the WindowsTM executable program WintensorTM is presented as an alternative to this kind of workflow in cases where the corresponding data are not (yet) in this database, where more control over the creation of the print files and 3D printing in two colors are desired for representation surface parts with positive and negative signs, e. g. those for optical activity (rotational power) and the linear electrooptical (Pockels) effect in α-quartz. In accordance with Franz Ernst Neumann's principle, restrictions on the number of the independent materials tensor components for the above mentioned physical properties by the point symmetry of α-quartz and the nature of the involved field tensors are explicitly mentioned. An appendix illustrates the crystal morphology of right α-quartz.
