Keep the things you love.

The handle on your beloved old cabinet breaks. The maker is gone. Keep the cabinet and design the part you need.

Concept

Repair it.

Replace a broken part.

Skip the hunt for a discontinued part. Design a replacement handle. Keep the same mounting points.

A favorite cabinet with a broken handle, then a replacement design Illustrative use case. A discontinued handle breaks; a replacement design keeps the existing mounting points. This is not a measured cabinet or generated CAD. Broken handleNew handle Same mounting points

About the handle concept

The brief specifies 96 mm mounting spacing, at least 25 mm of empty finger gap and a maximum length of 140 mm. The mounting pads are concepts; hardware is unspecified.

Sample brief, not a measured cabinet. The illustration shows the intended use; it is not generated CAD.

Recorded run

Make it fit.

Adjust a part that doesn’t fit.

A plate is too long for the space. Shorten it to the size you need. Keep the same mounting holes.

A mounting plate shortened from 50 to 36 millimeters Top-view illustration using recorded dimensions. Both plates are 35 millimeters wide with two 6 millimeter diameter holes 20 millimeters apart. The 36 millimeter result retains 5 millimeters of end material. This drawing is not loaded CAD. Too longShorter design 50 mm36 mm

What the dimension checks found

At 30 mm long, the plate left only 2 mm of end material against a 5 mm minimum. A separately confirmed requirement of 36 mm left 5 mm. The original 30 mm request did not pass.

The final plate measures 36 × 35 × 5 mm, with two 6 mm diameter holes spaced 20 mm apart from center to center.

This summarizes a retained numeric API/CAD run with explicit API confirmation. Passing these checks does not establish physical fit or readiness for manufacture.

Concept

Make it yours.

Make a grip easier to hold.

A narrow grip is awkward to hold. Broaden it and add a thumb rest. Keep the same mounting points.

A simple handle becomes a broader grip with a thumb rest Illustrative personalization concept. The two mounting locations stay fixed while the grip is broadened and a localized thumb rest is added. This is not generated or checked CAD. Awkward gripBroader grip Broader grip + thumb rest
Illustration · intended refinement
What would change and stay fixed

The grip would become broader and gain a thumb rest. The accepted handle's mounting points and empty finger gap would stay fixed as the shape is refined.

Starts from an explicitly accepted initial handle. This illustration shows the intended refinement; it is not generated CAD.

HOW IT WORKS

From your idea to your next part.

Design it, check it, and get ready to make it.

  1. Design

    Describe your idea and confirm the sizes.

  2. Review

    Explore the 3D design and check what changed.

  3. Approve

    Choose the version you want to make.

  4. Source

    Download files to prototype yourself or request a supplier quote.

WHAT WORLDKINETICS DOES

Your dimensions. Independently checked.

Astra writes Python using build123d. WorldKinetics executes that code in an isolated container, then independently inspects the resulting geometry against your confirmed requirements.

For the cabinet-handle refinement, nine checks cover the shape, mounting interface, finger clearance, requested change and exported files.

Astra cannot lower the thresholds or approve its own result. You approve the exact checked revision before getting its files.
