About this 3D model

A simple device to prevent your directional sunshade in place from rotating in the wind. The "staff" of the sunshade has 38mm diameter and the bottom part is design to fit a 50mm table hole. I wrapped the staff with 1 or 2 layer of electrician tape and it wont slip. Clearly, it won't resist to a storm but it works like a charm with light to medium breeze/wind.
