Roof window hook

Hook to open/close roof windows.On the picture, the hook is attached to a wooden broom handle. Printed with PET from pepsi bottles, 15% honeycomb infill, it don't bend nor break on use. It may break with PLA or bend with ABS at least with low infill, I believe that PETG can be a good choice. Feel free to give me feedbacks if you're printing with other material than PET. Update: Made v2, much stronger shape, seems to work well with PLA/PETG. Organic support, disabled support on the inside to prevent unnecessary trees to be printed.
