How it works

The premise

Stamp embosses, engraves or cuts logos, serial numbers and text into 3D parts as solid geometry. Bring an SVG, DXF or DWG, place it on a face, and the file you get back is ready to manufacture or print.

It’s a Qt desktop app running on OpenCascade, with installers for Windows and macOS on GitHub. The installers aren’t code-signed yet, so Windows and macOS will warn you the first time you open it.

What’s included

Emboss, engrave and cut, all producing solid geometry

Opens STEP, IGES, STL, 3MF and OBJ parts, and exports STEP, STL or color 3MF

OpenCascade geometry kernel with a Qt desktop interface

Big parts load in a background process, so an 80,000-face model opens in about three seconds

How it’s built

Stamp is built on Python, OpenCascade, PySide6, manifold3d and Inno Setup.

The repository is 99% Python by volume.

It carries 53 commits since Aug 2026, most recently changed in Sep 2026.

How the work is done

Every project here starts as a written spec, and the spec stays the source of truth once there’s code. The repository keeps a build plan with current status, an append-only decision log of where the code departed from the plan, and a handoff document that describes where things stand, including the unfinished parts.

That’s how one person keeps this many projects moving, and it’s what this page is written from.
