Remixed this hook to be large and fit No. 9 screws. The original model holes get to big when you scale it to this size. I also included a step file if you want to adjust it to your hardware. The hook I remodeled myself so it probably isn't a exact match. The hook is very strong and sturdy I printed in PETG with 4 perimeters and 25% infill. These hold up my ECHO trimmers easily.
