Strong - Rail Trolley Bicycle Hooks

Extra Strong Bicycle hangers.  Designed to work on a Trolley Rail.

I designed the hooks, to evenly distribute contact pressure on most bike rims internal surface. I tested multiple design variations in angles, rotations and size of shapes. I also tested various bed placements, with and without support.

This FINAL design and print orientation resulted in the greatest strength.

• For added strength, set sparse infill density to ≥ 35% and increase walls.

• For structural integrity and strength, the hook MUST be printed flat on the hex nut side side (see attached, screen capture).

• Convert holes to polyholes, for thread integrity, and set Top Z distance to 0.26

• Print with normal support.

• NOTE: Using 35% tri-hexagon sparse infill, using PETG tested maximum lift capacity, exceeded 105 lbs.

Hook Thread size is ½ - 14 UNS.
