Hypoidal

A Mac app for AI-made printable parts

Ask your AI for a part. Get a file you can print.

Hypoidal gives your AI a catalogue of mechanical parts built to the published standards. It finds the part, sets its sizes, makes it on your own computer and checks it, and the file is in your parts folder, ready to slice.

You
A flange nut for M6.

Claude uses Hypoidal
make_nut     { type: "flange", size: "M6" }
  → M6 flange nut ISO 4161, built on this computer
    14.2 × 14.2 × 6.0 mm, one closed solid
render_part  { }

Claude
Your M6 flange nut is in your Hypoidal folder:
ISO 4161, 14.2 mm across the flange and 6 mm high,
ready to slice.
Abridged from a real exchange. The part is made on your own computer, from the standard's own table.

From a request to a part you can print

  1. Install

    Download Hypoidal for Mac. It lives in your menu bar and needs nothing else installed.

  2. Connect

    Choose your AI app from the menu: Claude Desktop, Claude Code or Cursor. Hypoidal adds itself to its settings.

  3. Ask

    Ask for the part as you would ask a person: "an M8 × 40 hex bolt", "a flange nut for M6".

  4. Print

    Your AI makes it on your computer, checks its size and shape, and leaves the STL or STEP in your Hypoidal folder.

What the preview makes

Hex bolts

Metric, unified and Whitworth, any length the standard runs to, with a plain shank where it has one.

ISO 4014 · ISO 4017 · ASME B18.2.1 · BS 1083

Socket head cap screws

Metric and unified, with the hex socket sunk in the head.

ISO 4762 · ASME B18.3

Hex nuts

Metric and UNC, and PG conduit threads for cable glands.

ISO 4032 · ASME B18.2.2 · DIN 40430

Flange nuts

A hex nut with its own washer: a bearing flange that spreads the load.

ISO 4161

Domed cap nuts

Closed over the end of the bolt, for a finished look and no sharp thread.

DIN 1587

Every part checks its own numbers

Ask for one that cannot be made - a thread longer than the screw, a bore wider than the part - and your AI is told why, with the figures, instead of being handed something broken.

Yours, on your computer

  • Made on your computer

    Parts are built on your own processor, not on our servers, and the files never leave your machine.

  • Your AI can tell us

    When it cannot find a part, or something goes wrong, your AI can send us a note. That is how the catalogue grows, and it is the only thing Hypoidal sends.

  • What it needs

    A Mac with Apple silicon on macOS 13 or later, and an AI app that speaks MCP. Windows is to follow.

A preview that grows from what you ask for

Hypoidal starts with bolts and nuts. When your AI cannot find the part you asked for, it tells us, and that is what gets made next.
