Wavy drop down hook: filament saver

My most optimized drop down hook! It has internal waves which makes it much more resistant while using a tiny amount of filament. Prints without any support. Has holes for easy fastening. Print in PETG or ABS for durability. Great for to store skis for the summer.Boost MeI build niche models which take a fair amount of time to design. Boost are very appreciated.
