Customizable Rafter Hook – No Supports (Parametric Rafter Hook)
This is a fully customizable rafter hook designed for maximum flexibility and easy customization. Every critical dimension can be adjusted to fit your exact needs, making this model ideal for a wide range of rafters, beams, and hanging applications. This is not limited to 2x dimensional lumber - but whatever you may need.
The model is driven entirely by user-defined parameters, allowing you to quickly resize and adapt the hook without manually editing geometry. Below are reference images that clearly show all adjustable parameters and how they relate to the final shape.
Key Features
No Supports - the hook will lay against the build plate.
Fully parametric design – change dimensions, not geometry
Clean, printable geometry optimized for FDM printing
Strong curved hook profile with customizable depth, height and more.
Adjustable rafter area width and hanging hook widths.
Ideal for garage storage, shop organization, tools, cords, lights, or seasonal decorations
Adjustable Parameters Include
Rafter hook width
Hook depth
Hook height
Hook base height
Hook tip depth
Hook tip width
Base radius
Tip radius
(Refer to the included parameter diagrams for exact definitions.)
Printing Notes
Print orientation shown in images is recommended for strength
Use at least 3 wall loops. Recommend higher wall loops and infill for heavier loads. Since the size and intended use varies, it's difficult to recommend specific infill percentage and wall loops. I would suggest using a modifier on the hook area to increase infill / walls for increased strength where the bending force will occur.
Brim ears may be necessary for bed adhesion.
PETG, ABS, or Nylon recommended for higher strength and temperature resistance
Use Cases
Garage and workshop organization
Hanging tools, hoses, cords, or lights
Temporary or permanent rafter storage solutions
Custom-fit hooks where standard hardware doesn’t work
If you need a rafter hook that actually fits your space instead of forcing a generic size, this parametric model is built for you. Adjust, export, print, and hang.
