HEPH-3D — text to machine

Text to machine

Machines, not models. Describe one in a sentence and get printable, validated files, a costed parts list, and something that works when you assemble it.

Swept collision checks

across every joint's full travel

Printer-aware fits

tolerances your machine can hold

Wiring that survives

stall current, drop, connectors, fuses

Not a part. A machine, in parts.

Several bodies at once

Real mechanisms, real electronics at their true hole patterns, wiring, and clearances tuned to your printer and material.

Swept, not just static

Every joint is swept for collisions across its full range of travel before a single file is written to disk.

Plain Python, yours to keep

A design is a module exposing build() → Assembly. Saved to your Documents, never inside the app.

Claude Code, anchored inside the model

Not a chat widget talking to an API — a real Claude session running in your project directory. Click a part, ask about it, and the context goes in for you. Edit the design and the model rebuilds and reloads on its own.

Runs on your existing paid Claude plan — not API credits.

Nothing exports until it passes

A full validation pass runs before a single file is written — motion, printability, fit and power all checked together. Anything that would only reveal itself on the bed or on the bench fails here instead, with a plain-language reason.

Motion

Every joint swept across its full travel, not just checked at rest.

Printability

Walls, overhangs, watertightness and bed fit, judged in the print orientation.

Fit

Clearances measured against what your printer and material can actually hold.

Power

The electrical side sized for the worst moment, not the average one.

A tight fit your printer can't repeat is a coin toss

Printed parts don't come out at the size you drew them, and no two printers miss by the same amount. Ask for a fit finer than your machine can repeat and some parts will fall together while others split — so that gets caught here, not on the bed.

Every clearance in a design flows through one printer-and-material profile, so it always knows what your setup can actually deliver.

Calibrate once

Print a single coupon, take six measurements, and the profile learns what your machine really does — how holes come out, how the material shrinks, how thin a wall it will hold.

Retarget a whole design to another printer or material with one line.

A netlist will happily pass a robot that browns out

Stall, not running peak

A motor draws far more when it can't turn — which happens on every start-up. Size on running peak and the design passes while the robot doesn't.

Voltage drop with geometry

Worked out once the harness has a real physical path, so a long thin run can't quietly arrive brown-out low.

Connector ratings

The wire is rarely the weak point. Every connector is checked against the current actually passing through it.

Fuse sizing

Sized off the worst case, so it survives inrush instead of blowing at switch-on and teaching you to fit a bigger one.

Every component in the catalogue carries its real dimensions, hole pattern, keepout and current draw. Mount one and the standoffs generate at its true pitch — and the design always tells you which numbers have been verified and which haven't.

This build is for testing only. I won’t pass it on, publish it, or take it apart.

Before you install

macOS 11+, Apple Silicon and Intel. Python and the CAD kernel ship inside the app — nothing to install and nothing to set up.

The app is signed but not notarised yet, so macOS will claim it “could not verify HEPH-3D is free of malware” and offer only Move to Trash. Nothing is wrong with the build. Drag it to Applications, then run this once:

xattr -dr com.apple.quarantine /Applications/HEPH-3D.app

On macOS 15 and later, right-click → Open no longer works — Apple removed it.

Windows 10 and 11, 64-bit. Python and the CAD kernel ship inside the installer — nothing else to install.

The installer is not code-signed yet, so SmartScreen will show “Windows protected your PC”. Click More info, then Run anyway. That warning is about the missing signature, not about the build.

Linux, x86-64. Ships as a tarball with its own Python and CAD kernel. Unpack it anywhere and run it:

tar xzf HEPH-3D-linux-x86_64.tar.gz ./HEPH-3D-linux-x86_64/heph

The window needs your system’s WebKit runtime. On Debian or Ubuntu: sudo apt install libwebkit2gtk-4.1-0

Every platform needs Claude Code installed and signed in; HEPH-3D runs your own copy under your own account.
