This hook is designed to maximize strength while using only one screw. Instead of relying entirely on the screw for load support, the geometry transfers part of the force directly into the wall through the lower contact surface.

How it works

• Downward load is split between:

  • the screw (shear + partial tension)

  • the hook body pressing against the wall (compression)

• This reduces pull-out forces on the screw

• Improves stability under heavier loads compared to typical single-screw hooks

Design Features

• Single screw mounting

• Load-sharing geometry (mechanical advantage)

• Compact footprint

• Angled support structure for rigidity

• No moving parts → high reliability

Printing

• Material: PETG recommended (better layer adhesion and impact resistance)

• Orientation: print flat on the back face (as shown)

• Infill: 30–50%

• Walls: ≥3 perimeters

• No supports required

Installation

1. Use a suitable wall plug if mounting in masonry/drywall

2. Tighten screw until the hook sits firmly against the wall

3. Ensure the lower face is in full contact with the wall (critical for load sharing)

Use Cases

• Bags, backpacks

• Tools

• Cables

• Light to medium household items

Notes

• Maximum load depends on wall type and screw/anchor used

• PETG preferred over PLA for long-term load (less creep and better toughness)

• For heavy loads, always test progressively
