Parametric 3D Hinge Customizer

Design a hinge to your exact dimensions in minutes, right in the browser — then export it for 3D printing or machining.

What this tool does

Build a custom butt hinge by adding leaf plates, knuckles, and pin geometry, then setting exact dimensions with sliders. Every change rebuilds the 3D model in real time. Export as STL for printing or OBJ/GLB for further CAD work.

Who this is for

• Makers designing custom enclosures, boxes, and furniture
• Engineers prototyping hardware mechanisms
• Hobbyists who need a specific hinge size not available off-the-shelf
• Product designers creating custom joinery

How to use this tool

1. Set the hinge leaf width, height, and thickness
2. Add knuckles and adjust pin diameter
3. Position and scale each part in the 3D viewer
4. Export STL, OBJ, or GLB for your next step

Inputs

• Leaf dimensions — Width, height, and thickness of each hinge leaf
• Knuckle count — Number of barrel knuckles
• Pin diameter — Central hinge pin sizing
• Material thickness — Wall thickness for printability

Outputs

• STL — Direct input for 3D printing slicers
• OBJ — Import into Fusion 360, FreeCAD, or Blender
• GLB — Use in product renders or web viewers

Example use cases

• Laptop lid hinge — Design a matching replacement hinge and print it in PETG
• Jewellery box — Create a small decorative hinge for a handmade wooden box
• Cabinet door — Size a heavy-duty hinge for a workshop cabinet
• Prototype enclosure — Snap-test the hinge fit before ordering metal hardware

Frequently asked questions

▶ Can I print both hinge leaves as one piece?

Yes — leave the pin clearance at 0 and print as a single solid if you want a fixed joint.

▶ What material is best for a functional hinge?

PETG or ASA for outdoor use; PLA works for light indoor applications.

▶ How tight should the pin fit?

Aim for 0.2 mm clearance between pin diameter and knuckle inner diameter for a smooth fit.

▶ Can I scale the exported model?

Yes — STL and OBJ files can be scaled in any slicer or 3D tool.
