Design Concept
This 3D-printed model features a bolt-mounted backpack hook, making it ideal for securely attaching items to a bag. Its robust construction combined with the screw design ensures easy installation and removal, making it a versatile and practical tool for everyday use.

Application Scenarios
Primarily used to hang water bottles or other lightweight accessories on a backpack, providing convenience during hiking, traveling, or other outdoor activities by allowing quick access to essentials.

Printing Recommendations
It is recommended to use high-strength filaments such as ABS or PETG to enhance durability and impact resistance, especially when the hook needs to support a certain weight. A higher infill density is also advised to increase structural strength.

Assembly Instructions
Place the hook on the backpack strap or desired location, then firmly tighten the nut onto the bolt. Ensure proper alignment to maintain secure fastening.
