About this 3D model

I wanted my air ventilation grill in color that matched my windows. So I copied my existing grill made by Fresh AB. The STLs are for a 75mm pipe. Enlarge the model to 132% for 100mm, and 164% for 125mm pipes. My work is release under CC-BY-SA. But Fresh AB might have IP right to this design that prevent it form being used commercially.
