About this 3D model
I wanted to have a lenshood for my videocamera. The inner diameter is 7cm. I also uploaded the catia source file, so you can adjust it as needed. The full version and the first halve version have a wall thickness of 2 mm. I also uploaded a 1.5mm version, for those who want to save some material. (About 2 meters of 1.75mm filament per halve)
