Hook replacement for a generic rotating car air conditioner vent holder mount support for Samsung cell phones. It could be compatible for other identical supports used for different brands. You can check the pictures to be sure if hook would fit ok (4 screws needed). The piece was designed by a friend of mine, Edu G. for replace the broken original one. Thanks to him for his design expertise and patience with my recommendations during the test printings.The piece has been printed with PLA 1.75 filament using Cura slicer software with a 0.4 mm nozzle. I got better results choosing these main settings: I recommend choosing a platform adhesion to avoid defects in the first layers of the lower ring due to its thinness that could difficult the attachment of the entire structure . Please check pictures to see how it is. However you will obtain the best result for this lower ring if flip 180º the piece, but the need of printing supports makes you will get a base with worse finish.
