Stop printing weak, easily broken S-hooks that do not fit your closet rods or shelves. This generator allows you to dial in the exact dimensions you need for a perfectly fitting, heavy-duty hook. The mathematical sweep algorithm ensures a continuous, strong structural curve and perfectly rounded tips for a premium feel.

⚙ What can you customize?

• Top & bottom diameter: Set the exact inner size to perfectly hug your shower rod, closet pole, or wire shelving.

• Hook width & thickness: Scale it up for a heavy 20kg load (like backpacks or tools) or thin it down for hanging light plants and kitchen utensils.

• Wrap angles: Control exactly how “closed” the loops are. A wrap angle of 180 creates a half-circle, while 240 creates a secure lock that will not easily fall off when bumped.

This is a robust, support-free print optimized for strength.

• Material: PETG, ABS or ASA is highly recommended if you are hanging heavy items or using it in a hot environment (like a car or bathroom). PLA works great for standard indoor organization.

• Walls: 4 to 6 walls. This is crucial. More walls equal exponentially more strength for load-bearing hooks. Do not rely just on infill.

• Infill: 25% Gyroid or higher.

• Supports: 100% support-free.
