This device prevents lateral incidence of sun rays which affect your vision during driving. It is meant to increase comfort and safety. Please use wisely, never put it in a way that doesn't allow you to see the road or your side mirror.
The model has been printed with Desktop 3D printers using PLA material, although using other filaments is also possible. The standard way to print it is with the front face upwards and using supports on the back side.
Upon request we can design a customized version of the model, including but not limited to: a different shape (i.e. the dog model) or a different design on the front face. The model has been designed to allow space for publicity on brands, logos, or free design. Please contact the owner with your idea or application and we can discuss further details.
