This twist and lock hook is perfect for those times you need another spot to hang something in your car! It is recommended to print in ABS or ASA and to increase infill if needed for something heavier like a bow (which has been tested and passed!) Has also been successfully tested with PLA for lighter items but in hotter weather PLA most likely wont work as well. I am working on making some other versions with longer/thicker arms and will upload soon! I also need to go back and grab the file for the thicker version seen in the picture and add that too later today!
